I would like to be able to change the Display Name freely.

Since users have unique IDs, it seems to me that Display Name should be able to be changed freely.

There are various situations where we want to temporarily change the Display Name, such as temporary memes, team division in games, etc., role-playing in plays, etc.

I think this is a system that cannot be changed for a certain period of time for security reasons, etc., but a paid VRC+subscriber would have some reliability.
