The only thing that compiz can't offer it a "non composited" window manager 
mode. Even if KDE/GNOME would decide to use compiz, then they still would 
need to maintain kwin/metacity. And compiz will never act exactly the same 
like kwin/metacity.

My tests showed that it would be relative easy to disable the 
composite/painting code in compiz. Compiz then acts like a normal window 
manager. The problem is that we would need to rewrite the window decorators 
to create "reparented" window decorations in the 2d mode. A new (or an 
extended version of the current) decoration plugin would handle then the 
reparenting of the decorations. 

Maybe someone should convince David that we need a "2d only" window manager 
mode. Such mode should increase the chance to get accepted by the desktop 
environments, because they could then drop their normal window manager.
