Are there any tournaments that treat less-represented groups preferentially? These less-represented groups could be women, transgender players, etc. As of time of writing there's only one woman in the world's top 100 players by rating, and I don't know if there's any transgender player there either.

I'm thinking in particular of tournaments where the organizers reserve some space explicitly for these less-represented groups. For example, suppose one of the 8 spots of the Candidates Tournament were reserved for the Women's World Champion, that would qualify (of course this has never happened). For the purpose of this question I exclude women-only tournaments, unless these tournaments gave special privileges to players who transitioned from male to female.

Further questions: if this has happened before, how did the community react? If this has never happened, has it ever been considered?
