Tell me about it.

The whole /19 thing started as a bad idea, and has propagated because other
people picked up on it and said "yeah, ok" and then formulated policy around
it - instead of whacking the first person with a wet noodle.

There are some providers out there who think that there's no reason they
should have to spend money on RAM and CPU in their core routers.  There's
a curious correlation between those folks, and the ones with the largest 
number of route announcements too. :-)
