the proposal for arbitrary custom profile fields is better than this. it's neutral and if people want to use it for pronouns or XMPP accounts or anything else, it's nobody's business. just do it like pleroma.
We might loose 60% of our right-leaning user base, but we will display pronouns for users that add them to their profile. We are here to serve users and if users want, even if it is a minority right now, they will have it.
