As so many v6 network tends to leak fulltable to others, without properly 
transiting them (examples: 2497, 3257, 6175 ...), such AS pathes don't 
surprise me at all.

As long as (mainly) incumbents think "we peer only v6 with existing v4 
peers", regardless of the v6 deployment of some v4 networks, there will be a 
deadlock forever.
