Well, people don't have to use it if they are always going to have a
full-screen window covering it.

If GNOME at some point blesses a compositing manager, it would
probably make sense to have the compositing manager draw the

transparent, or have some way of communicating to the CM what icons
etc. should be drawn on top of the root.
