I did say have both, right? You can have analyses assume Level 100 OU since that's clearly the Smogon standard, and people playing Level 50 OU can modify their EV spreads accordingly, if even necessary at all (sometimes it is but for 4/252/252 etc. spreads it isn't)
Also it's not JUST me who has a problem with spending lots of time leveling everything up to 100; I apologize if that's what you got from that but there are other people who don't have the time to do that.
You could already adjust your EVs according to level 100 analyses, and just test it on console. I'm really not sure I understand the point of creating an entirely different metagame for very slight conveniences for a small minority.
Especially if you're not even trying to get new analyses for level 50 pokemon.
