So, I'll admit that I MOSTLY play monotype so thats one grain of salt for what I'm about to say, and I've not had much time to play gen 9 regardless due to college reasons (so there's the second grain of salt), but because however this whole thing resolves will affect the way the game is played even after I have more time to actually play the game, I feel obligated to at least throw out my thoughts.
Firstly, I'm not really a fan of 'restricted tera' because, to me at least, it comes off as contradicting the whole 'no complex bans' thing that has been a persistent stance, and sort of feels like just kicking the can down the road because eventually someone will just find some other way to break the mechanic (if, for the sake of argument, we do presume that its broken). The only one I've seen that lets the mechanic persist that I'm sort of okay with, personally, is showing tera type at team preview. And to be entirely honest, I'm not even that much of a fan of that because that isn't information you'd get on-cart, and it would go against other bits of hidden information like moves, abilities, and items. If making tera-type become public knowledge happens, it opens up the can of worms for all the rest. And hey, maybe knowing what set the enemy has at preview could actually end up being a good thing for competitive play, I think there's an honest argument to be made there if you want rankings to truly be "who built a better team and who played said team better" and filter out people winning by running whacky sets that only succeed by taking players by surprise (oh and also everything dangerous because it can run whatever set it darn well pleases and forces you to play around that unknown becomes much easier to handle), but the point I'm getting at is that we don't CURRENTLY play that sort of meta, at least not yet, and if the final call becomes making tera known at preview then you open the floodgates for going all-in on that sort of direction. Whether thats good or not is up to you, I'm just pointing out the implications that sort of precedent sets.
Secondly, I honestly and truly do not think ANY action should be taken UNTIL the home update drops (sorry for yelling), period, if only because
A): we simply aren't playing with the full pool of pokemon present in the game's code yet, it doesn't hurt to wait a bit to be sure.
B): from what I've observed at least the ou meta is only just now starting to actually settle now that we have some actual rankings and people are figuring out 'optimal' sets and the like, so some time should be given to observe that to be certain.
C): and this one may be a controversial take but is one I want to make anyways, I legitimately think that holding off on doing anything about tera in ou, and instead seeing what it does in the lower-power environment of lower tiers could be a good way to be better able to verify if tera is the problem in 6v6 singles, or if the problem is a small pool of abusers that go from "strong" to "there is no reliable method to deal with this thing". Plus, on a smaller level that should at least be considered, if Tera ends up being perfectly balanced and enjoyable in the lower tiers, having it universally banned from all the usage tiers because of OU being unable to sustain it would be a huge disservice.
We know there are things that abuse terastal. But please forgive me if this sounds heretical, but there are also things that abuse items or specific moves to an extreme degree, and we still call the pokemon the problem and not the tool it is using. Nobody would complain about Scarf Chi-Yu if it wasn't so strong that even being choice locked didn't matter that much, but we also aren't going around saying the choice scarf should be universally banned either, just as an example.
As an aside, I still don't see why just, making a Tera-OU as an OM is so impossible if tera IS banned. There is an active playerbase for AAA and hackmons, and those are formats that are outright impossible/illegal on-cart, so from a purely playerbase angle I'm positively certain you would have an active one from all the people who like tera and want it to stay, especially if the inevitable suspect is particularly close. Tera, unlike dynamax, seems to honestly have enough people who want it to stay that outright banishing it to Anything Goes/Ubers is a massive disservice, and the argument of "just play those if you like tera" is just as bad as all the terrible arguments for people have made for keeping certain things unbanned (at least the ones that aren't stuff like "blaze-blaziken in UU", I'm talking people about people who unironically go "just run water absorb to beat dracovish"). There is a difference between people who want to use the generational mechanic in a tier with an actually reasonable power level, and people who just want a brainless win-button.
I'm aware that setting up a 'TOU' OM would take resources but I HIGHLY doubt its impossible to find enough skilled players who both wants to play it and is able to moderate and do other council duties for it. Likewise I don't really buy into the "don't split the meta" argument, at least not if the OM just remains constrained to 'only' being OU Ft. Tera, not Ft. things that take tera too far. The main OU ladder is never going to die until the day gamefreak actually tries to support 6v6 singles themselves, and I can't help but feel that, even if it ends up unpopular with most, that tera still has enough actually competitive and creative teambuilding and mid-battle aspects to justify letting it be a meta people can play if they want to, something that dynamax most certainly DID NOT have.
From what I can tell, a lot of the hardline "no alt ladder" stance (as well the controversial houndstone ban, if I'm being honest) seems to come more from administration rather than the OU council (who from what I've seen have been respectful and have been trying to be pretty evenhanded on the tera matter), and if that the case, then I think there's an issue with site administration refusing to be transparent and actually open to debate more than anything else. To the OU council, if you got this far, sorry for making you sit through my little rant at the end there everyone. I respect you guys as players, you seem to be alright people, I just had to voice the totality of my thoughts on all this, and thank you for putting up with all this.
