I agree that was the IETF's direction, but it is also a different
solution.  As I see it, the problem space has three, high level,
diverging paths:

A Multihoming happens entirely at the host, making PA-only possible.

B The routing system can scale to PI, so everyone has PI.

C Neither A or B is possible, so we attempt to decide who is worthy
  of PI.

It seems to me we are in case C now, the IETF tried A several years ago
and gave up, and the IETF is now trying B.  (roughly)

Which raises an interesting question, why hasn't SCTP taken off more?
