I think there's also the overlooked solution of not designing a setting with a bunch of stuff players might object to.I've mentioned the GM having a tiebreaker vote several times. Giving the GM a tiny bit of authority more than any individual other player is not even close to the same as they having all authority this side of everyone taking a walk. It just says you probably want to have somebody be able to do so, and while you could have a designated player who does instead of the GM, there's no particular reason not to have that vested in them, too.
If you can spend 6 months designing a setting with just 3 races, and not having any logical way to have more, why not just, ya know, spend that time designing a setting with a place for everything?
