Yep if they did it for one, they’d have to do it for everyone.
Certain extra features like co-op or performance stuff is obviously fine, but not having a Series S version would screw over half the Series userbase and they’d rightly sue, it’d screw over the store (which doesn’t split out Series tags), xCloud (as it often uses the S profile) and a future handheld if that used the S profile, and not least would be giving in to the circus around blaming the S for everything.
Better to not have the game that do something so alienating due to some devs who’ve behaved pretty appallingly (and even Xbox seems to think so as they very rarely comment on deals as it’s not a good look getting into fights with devs).
I’ve got a PC so could get the game and was considering it till they started playing silly buggers - but I don’t reward stupid
