I agree with everything you just said. Where does that leave us?

The whole IPv6 PA-everywhere idea that came out of the IETF has enough
glaring technical deficiencies that it won't fly. Is CIDR and the
needs-based justification we've employed for the last 12 to 14 years
the best answer there is? Or have we learned enough about routing and
addressing in the last decade to come up with a better answer for the
relatively clean slate afforded by IPv6?
