"A couple of thoughts on this. First, we definitely shouldn't be offering edit options to people..."
For types where I have no rights, the type editor still offers me the option to change things. Only when I try to change them will it tell me that I'm not allowed. This includes just trying to look at the options for enumerated types.
Rather than offering me an option and then refusing to follow through, it should disable controls I'm not allowed to fiddle with. That way the interface will better reflect the underlying reality.
