This does sound like a better approach.

That still doesn't give us any way to delete decorations when they are no
longer needed. At a minimum we'd also need to send an event/message when
we want to switch layouts. The user could always do this in his/her config
file, but it'd be nicer for layout writers to not put this burden on their
users, and to be able to rely on *always* getting notified when they are no
longer in control of the screen (and thus need to clean up anything they've
stuck on it).
