< rant >

there once used to be 'swamp' space, down in the low 190s where /24s
were expected.  and folk/rirs tried to keep shorter aggregates, e.g.
/19s, as the norm above swamp (negotiated at ietf/danvers).  in those
days, one could actually filter above swamp on /19.  for a while, one
could even have classful filters in A and B space.

and a soda pop used to be a nickel or a dime.  those days are long
gone.

i expect that we will accept prefixes longer than /24 as things get
tighter.  and i doubt we can socialize constraining that fragmentation
to one section of the space.

it is a tragedy that cidr and an open market has helped us more than
ipv6 has.
