Not really. There's a fair bit of creativity within the sets that these Pokemon can run, and I think that's fine. I don't think creativity should be measured on "how many viable Pokemon we have in a meta" or "how centralized a metagame is". The reality is that as the pool of available Pokemon get smaller, the more concentrated a metagame becomes. That doesn't diminish the amount of creativity there is in a given metagame.
Teams in SV OU that aren’t HO require these in order to succeed in the tier from most important to least important.
-Tusks or Cinder (Sometimes Iron Treads) unless your running Boots spam.
-Second Gambit answer (Usually Molt, Zama, Valiant, Samu-H, etc)
-Speed Control (Priority, Booster, or Scarfers)
-Fairy check (Ghold, Molt, Glowking, Amoonguss, Pex)
-Ghost check (Ting-Lu, Garg, Tran, Gambit)
-Ground Immune (Zapdos, Lando, Dnite)
-Fighting Resist/Immunity (Valiant, Ghold, Glowking, Zappy)
-Wincon (Valiant, Dnite, Bax, Dozo)
-Bax check (Balloon Steels, Zama, Valiant, Dozo, Garg, Azu)
-Breaker (Bax, Hoopa. Samu-H)
-Garg check (Amoonguss, G-Knot Glowking, Covert Ghold)
-Electric Immune, preferably one that matches up well with Zapdos (Ting-Lu, Sandy Shocks, Clod, Treada, Gastro)
-Water Resist/Rain Check (Amoonguss, Washtom, Pex, Dnite, Bax, Dozo, Tera Water)
-Hazard Setter (Like half the tier does this, lmao)
-Pivot (Glowking, Pult, Sneasler, Cinder, Lando, Zappy)

Seems to be a pretty good selection of mons from the OU tier, and that is without mentioning other non-OU mons viable in the tier and Tera. However, there are things we are lacking in the tier.
#1 Hazard Removal: I don’t think I need to explain this.
#2 Offensive Fairy Checks: A majority of Fairy checks outside of Glowking, Ghold, and Molt are rather passive. Not to mention most of them lose to Tera Steel Sub-CM Enam, which means you also need something that can outspeed and threaten OHKOs on it while being able to live a +1 hit from EP/Moonblast. Amoonguss needs to slot in Stomping Tantrum to beat it. Skele can hit Enam through Sub but isn’t fond of eating EP. Clod beats Tera Steel but without Pjab, it loses to Sub-CM anyways. This is prob the least talked about problem of the meta and its a consequence of the Volc ban and mons cut from the game like Melm, Cele, etc. (also the psychos who thought giving it EP was a good idea)
#3 Lack of consistent Garg checks: Just like with Enam checks, most of Garg’s checks are either Regen walls or require an item/moveslot. Covert Ghold has other benefits like dodging Discharge paralysis, but no Balloon means you miss out on a Bax check. Mons like Wake and Lando require Sub to beat it, but to do so, they need to safely switch in and assume the Garg player won’t go for Salt Cure. Things get more complicated with Tera and Curse/ID that let it dodge 2HKOs and break the sub effortlessly. Some Gargs run EQ to hit Glowking, requiring G-Knot and Tera Grass to 1v1 it. This is likely to be solved with Clef and Gliscor returning to the tier, but as of now, this is a teambuilding issue.
It is possible these issues will be resolved in the Teal Mask meta assuming Defog distribution rises, the legendary trio turns out to be part Poison, and Gliscor/Mandi/Clef coming back.
