For the record, as a spouse of someone that's at least partially off the binary + personally part of an oft misunderstood minority myself (asexuality), I totally get genderless/nonbinary being a legitimate thing.
All I'm saying is that it's still not the job of this game or pretty much any other game to cater to those minorities. Trans/NB/etc stuff may simply not be a thing in the world of this game, and nor does it have to be, particularly when it doesn't fit any particular critical narrative of the story. It's sort of how I will never expect, nor do I feel there should be, any openly asexual-presenting character in the game. There just isn't any reason for there to be one, and I'd rather they not just shoehorn one in there for the sake of "diversity!" like some other games, TV shows, movies, etc. have taken to doing lately (sometimes, it feels like, at the cost of actual storytelling ability)
