Are you sure this is true?  My (admittedly fuzzy) memory tells me that
un-queued traffic effectively reduces the size of the pipe for the
queued traffic.  This of, of course, has undesirable results on
min-rates, but isn't as severe as dropping traffic altogether.  If we
don't drop unqueued traffic, does forcibly installing a default queue
still make sense?  The cost of a misconfiguration is significantly
lower in this case.  I'm curious what your thoughts are.  I dont' feel
particularly strongly.

I haven't read the patch yet
