Well, it makes sense to me:
  http://www.mail-archive.com/wm-spec-list gnome org/msg00557.html

The consensus of implementations seems to be moving towards WMs and
CMs being the same thing anyway, and there's already at least one de
facto, undocumented standard for CM behavior that "illegally" uses the
EWMH-reserved _NET_WM namespace (_NET_WM_WINDOW_OPACITY).  Better to
bless such things and bring them into the spec than let them
proliferate.

(I think, though, that the _NET_WM_CM_Sn selection has "WM" in it
because "_NET_WM" is the EWMH namespace, not because it's the "window
manager" namespace, if that distinction makes sense.  So it doesn't
bother me.)
