I'm not sure I'm ready to sign on the dotted line with respect to
every aspect of your argument here, but that definition seems OK to
me.  In practice it's likely that a lot of the NOTICEs we emit now
will only be seen when restoring dumps, and certainly in that case
it's just junk anyway.  So I think this would be fine.
