I agree, preventing migration of windows seems to be closing the barn 
door after the horse has already bolted.  If someone can set properties 
on your window, then they can sniff/synthesize events, set other 
properties and delete windows.  They can map other windows that 
impersonate your window.
The games over, the horse has bolted.
