Sounds more like a way to make almost everyone annoyed. All the text would be more awkward for every player, so people who don't care about NB pronouns would justifiably be annoyed: it would actually be a case of identity politics making a product clearly worse (granted, it would be conservative identity politics that caused it), unlike all the times conservatives get mad because minorities exist in media sometimes. And NBs would know the dev put in more work to change all lines of text to remove all personal pronouns just to avoid adding another option for them. It would be a much more direct "fuck you" than doing nothing at all.

I wish English did not overuse pronouns (personal or otherwise) because of the ambiguity and misunderstandings caused by pronouns, but if its gonna change its going to have to start with people changing how they use the language, not some 8 year old game to try to shoehorn in.
