Suggestion is simple: Make it possible for Bots, to actually see, if a user has nitro (if yes probably also what kind of nitro), is in HypeSquad (And perhaps what type/house), is a official staff, is partner and what else could be seen as a badge on the users profile.
There is the User object (user structure) which already provides this info. But (at least as I understand it) is that behind a different OAuth2-scope (identify), which can't be used by a bot, or at least only through some changes in code and/or the link?
I know that this could give potential for abuse (like only allow users with nitro or a certain HypeSquad house to join a guild), but lets be honest: What on discord's API doesn't give a potential for abuse (And maybe is already abused?)
This would give Bot-developers a really nice way, to f.e. show custom badges/emotes on a Embed with user-info, or tell others if someone of the mighty staff-team joined the guild (Which could be possible).
