Sure, but there's a point where the work involved (even from scratch) isn't worth the actual player use of a feature. This would be like adding Vitiligo skin textures. It would be awesome to have those people represented and go towards making awareness their particular challenges and normalizing their appearance... but it's 1-0.5 % of the population. A lot of work for a minimal userbase.
This whole topic is crazy baiting, nobody wants to exclude or hates nonbinary people. Sure we'd all love to include everyone and make everyone happy but this is a QOL for a tiny userbase.
The whole thread has just been virtue signaling and sarcasm.
