Well, it's not like the spec is written in stone (yet). I've thought of 
the stub idea, but I believe that it is really ugly and unnecessary. 
Since there is no change to the semantics, couldn't the WG have some 
remedy (perhaps unanimous consent) to fix this issue before the standard 
is fully petrified?
