I think you underestimate the tendencies of ISPs all over the world
to leak peering routes towards their transit providers.
Contrary to popular belief, leaks through peers in remote regions do
not always result in huge AS_PATHs which are never selected by the
rest of the network. For example, some of the most remote and poorly-
connected ISPs that F is announced to from local nodes are transit
customers of international, default-free carriers.
