The knowledge that route (a) was originated by AS (x) is only meaningful insofar as one has some set of high-confidence beliefs/expectations about AS (x). However, if AS (x) can change hands at will, henceforth no such confidence will be possible for the overwhelming majority if not all ASes.

Further, this is the first I heard of this being an issue, it's never been brought up in any of the several RKPI talks I've been to.
I don't classify myself as an RPKI expert, and I would say that Gary's concerns are additive to what Tom and I have expressed. I don't think that requiring ARIN to issue new ASNs will necessarily prevent ASN reputation hijacking, however, since you have the same revocation problem as the RPKI certificates... ASN validation would suffer from the same issues.
