Yeah, the more time goes on, the more convinced I am that this Vecna adventure is going to feature some sort of partial-reset of their multiverse - something to give them cover to get rid of anything they now consider controversial or problematic, while simultaneously allowing them to retain whatever elements they want to keep.
Which is fine, I guess - it's their multiverse to do with what they will. Unfortunately, 'problematic' is very much a moving target, so any hope this is a one-and-done project is unlikely to be justified.
