We could match mutable=true against properties intended explicitly for 
an action. It's a bit more difficult with global options or options 
intended for a group of actions. But sure, it can be done. If no action 
in the targeted group of actions have a mutable property with some name, 
regardless of what that group is, then that name is illegal. That would 
be very helpful indeed.
