I think you missed my point.

This is not exactly an issue of how your traffic, once routed
through your providers router, traverses their backbone. Rather,
its an issue of the ability (or inability, as it were) to sloppily
engineer capacity due to the nature of defining excessively
high ratios of virtual circuits-to-aggregate ingress bandwidth.
