My only concern with this approach is that the server quietly reverts any attempt to change the visibility property if the override flag has been set. Because there's no feedback to players, this could lead to player confusion and complaints to either the server admin or ourselves, which isn't ideal.

I'd prefer if the fact the visibility can't be changed was made as clear as possible to player attempting to change it...

Also, if the change is reverted (i.e. denied), it shouldn't be necessary to resync the team's chunks, right? Since nothing's actually being changed.

Any suggestions on where I could implement that?

The UI would still show that the setting has been changed even though in the background it has been reverted. That's why I send a resync.
