I can agree with your points, but it seems to me like people who want to use they them or he/she on the opposite gender are gonna have a worse game, if it means so much to them, let them?
Yeah they will get a weird experience, but likely they care more about having the character they make be like them, then the story feeling natural.
Just use the pronouns that dont feel jarring to you.
Hopefully larrian dont waste loads of resources polishing the non binary world so if actually makes sence, maybe our custom character need badges saying they/them so dror knows what pronouns to use when addressing the MC
