This is more or less intended to tie in with whatever avatar performance system is planned for the future.

If the borders of the avatar profile pictures in the avatar list and pedestal prefab in worlds had some kind of generic indication of how well optimized it is (Like green, yellow, red), I believe it would help create pressure for non-creators and creators alike to start using well performant avatars.

Or at least help make people aware their avatars might be causing performance issues for people.
