I'm developing an asset in Udon that will allow players to teleport, send message, and perform other actions towards other players in the instance.

I'd like the UI to not show players who are blocked by me, or players who are blocking me.

I'd like Udon to provide a feature that can make such a determination.

For example, something like VRCPlayerApi.IsBlocking.

Such a feature would also help prevent accidents where two people who are blocking each other end up matching up in worlds that encourage random interactions between users.
