Is the username rollout finished though? What happens in this case if the user still has a tag?

[Chew]

Yeah you'll want a misc util method for friendlyName() that gets the tag if discrim > 0 or just the username otherwise

Discord will be automatically changing tags to usernames on March 4th from what i've heard, we could wait until then?

Yes, once that's done we can remove tag support. I think bots may still have tags but not too important

Usernames are now fully migrated, we could move ahead with this PR 👀
