Yeah, but this particular one I believe makes Layouts fully extensible.  It
removes the need for unsafe behavior that's already been implemented
(LayoutHooks, in particular).  After this, all I forsee is a refinement of
the API to make it safer and simpler (not that I see how to do so, but I am
sure it must be possible).
