I feel almost silly to point out a simple solution, an extension
of the above, to the smart crowd here. But doesn't every one
at the very least filter routes from peers/customers to reject
ASes 701, 3561, 1, 1239 et al. (unless of course the peer is
one of them). Minimizes the damage right away. Of course, not
as tight as using routing registries. Has saved us a few
times.

Now that is a positive side to the industry with a handful
few huge, transit-free, players. Just watch the mergers
and acquisitions news to stay current :-)
