 Let's turn the question around once more: Why shouldn't the user be able to 
disable compositing? As you said in your first mail, compositing should be 
enforced only if supported, so non-composited mode needs to be supported too 
anyway. The benefit of removing a checkbox seems far too small compared to 
all the potential trouble.
