Ah, so if I understand correctly, the fact that libwnck's right-click
menu for the tasklist showing items as sensitive that shouldn't be (i.e.
move or shade on a minimized window), is actually a Metacity bug for not
updating _NET_WM_ALLOWED_ACTIONS.  Correct?

If so, we can chuck my proposal as there's no other use I had in
mind.

Well, as I said above, it looks like we can chuck my proposal.  However,
it'd still be really nice to have some clarification.  I read through
the thread and couldn't see any conclusion reached.  What I did find was
that it appears Sasha equates IconicState with minimized and that he
defines shaded as a subset of NormalState
(http://mail.gnome.org/archives/wm-spec-list/2001-December/msg00007.html), yet the Metacity implementation definitely doesn't do that (it does IconicState == minimized || shaded).  And you pointed out in that thread that the ICCCM didn't equate the IconicState and minimized and that the ICCCM defined IconicState to be ambiguous.
