Every user in VRC has a name tag. Of course, this makes sense.
However, being able to "force hide" your nametag so that it doesn't show up AT ALL (and not just by pressing the key to hide nametags on your client) would open several interesting possibilities:
A player could go into a world, say with a scary avatar, but no other user can recognize the user as a player/user. (Because no nametag :) ) He could as well be part of the world, an asset or NPC.
Imagine role-playing in some of the scary worlds in VRC, like haunted prison or wherever.
I thought the BIIIIG and BRIGHT nametag over a player not optimal since it automatically gives away "you are just another user" and no "scary ghost". Think about. It would be super simple and could add to immersion and some fun in worlds.
Again, this is not about that someone on their client can hide nametags. We can do this already. This is to give people a way to not reveal the fact that they're players to others.
It would be something optional and your opinion about this may differ, but any more option and choices to have are good!
