There's already a third party extension that does this.
I could maybe see it being a thing in the profile card.. but I think tags or anything involving the username is a really bad idea.
To be honest I'm camp "I've never seen this issue in any chat ever." but we could meet halfway.. so profile card if that solves it for you. It doesn't impact chat visually and you can still figure out someone their pronoun if they feel the need to add it.
