I feel this is really a moot issue because after IPv4 runout, the
RIR's won't HAVE /24's to hand out, even if they wanted to, much
less having /22s.

I also feel it's a slippery slope to permit /24's because if you
do your going to permanently establish them - because by the time
the orgs that get them want to "trade up" to a /22 they won't
be able to since the RIR's won't have any more IP.
