I'm sorry, but I still do not understand why a client, that has code in 
it to "request compositor handle resizing" cannot also have code in it 
to know that it may not get a button release event.

There is no need for a flag on the release event, as it may be sent 
before the "request compositor handle resizing" message is transmitted 
and thus can be sent with the flag off. Therefore the client must be 
able to handle it no matter what the value of this flag is and therefore 
the flag is useless.
