Depends upon whether such limits serve a legitimate purpose...So, I love DMing campaigns that focus on periods of time gone awry or fantasy/history as a background to gameplay.
So if a DM said I have a campaign idea, but you can't play elves or mages or wombats in drag or whatever, is that a deal breaker or do you accept that the game can be fun within set parameters?
No wrong answers, just opinions. Understand this isn't about writing the DM's next novel or railroading just there is a reason that these don't exist. (Like no samurai in a Norse setting).
Alternatively, what would keep you from playing a situational campaign and why?
If the "no elves" and "no mages" are because the game is about curing the spell-plague before all magic is gone? Sure.
If they're because the world is low mana? sure.
If it's simply "I don't like wizards, and only allow sorcerers, and all elves are NPCs" I'm likely to walk.
It is about why, more than what.
