Before we decommissioned our last open peering fabric, source-routing
was important to make sure your peer wasn't pointing default (or
similar) to you. With the advent of private (and far more limited)
bilateral peering as a preference to fabric based peering (at least
among the ones who set peering policies globally) this has become
less of an issue.
RFC 5095 aside.
