Adding an api so the client can tell the compositor whether it obeyed 
the instructions sounds unnecessarily complicated, and also means the 
compositor has to be ready for either case.

I think all that is necessary is that clients must obey the instructions 
from the compositor.

And you are going to need flags at least for each of the 4 edges, and 
furthermore for the "titlebar". You may also need flags for the shadows 
on all 4 sides. For an obvious example "maximized" may want to turn off 
the 4 edges but not the "titlebar".
