I've heard apparently non-drunk people suggest IPv6 link-local addresses as BGP endpoints across exchanges, too.
(Half kidding, but still ....)
RFC 6752. One observation on this thread: some networks have customers who react badly to unusual things seen in traceroute. Sometimes the margin on an individual customer is low enough that one support call displaces any profit you were going to make off them this month. It's understandable to me that such network operators would choose to carry IXP routes internally in order to avoid that potential support burden. I don't pretend to have any universal good/bad answer to the original question, though. I don't think the world is that simple. Joe
