@c0debabe in terms of non-binary pronouns, we had to invent what is often considered as a neopronoun, "iel", which is a middle ground between "il" (masculine) and "'elle" (feminine). Some people prefer to use "ael", which isn't a mix between masc and fem, so it often fit better to people feeling outside of that duality.
Important thing to consider: this is purely a subjective approach I have there, it's based on the non-binary people I know and how they use their pronouns, it's absolutely not something set in stone.
