And whilst on the subject - If we give a climb above the SID level - do not ask "is that unrestricted?" - It means climb now! The new clearance negates the old.
Why have the SID altitude restrictions then if you are only issuing altitudes that coincide with the SID. There is no reason to have them. The same with STARS. A decent instruction when you are cleared on a STAR doesn't negate the STAR restrictions.
