A client may ask, but the server may not support the extension. If it doesn't, 
then it won't reply and then the client will have to draw its decoration.

But your other suggestion that the compositor tells clients not to draw is 
even better. 

The only detail is that this extension doesn't exist yet, so the compositor 
needs to check whether the client acknowledged the message. If it didn't, then 
the compositor must assume the client is decorating itself.
