No you are misunderstanding how this will work.

The compositor can intercept any keystrokes it wants and use them to 
manage windows. In addition there should be a way for clients to tell 
the compositor "I was not interested in this keystroke, do what you want 
with it". If these are both implemented there is no need for clients to 
understand window management shortcuts at all, except an informal 
understanding of popular key layouts so neither steps on the other's key 
usage.

Dragging in the titlebar/etc is done by clients detecting that the 
mouse-down is in an area they are not interested in, such as "dead" area 
of the window, or in the title (but not on a button) or window edges. 
They then tell the compositor "I am uninterested in this mouse-down, but 
I think it is a title/edge/corner/contents drag, please handle it". The 
compositor can then do all the window snapping and restrictions it wants.
