But I think a large part of our disconnect here is that there are lots of backbone-level ops listening to lots of edge-network ops, and failing to take into account that the latter group has *substantially* different constraints on their engineering decisions and practices, and that both groups' limitations are inherent in what they do. Certainly the backbone has to not mess with stuff. But that doesn't mean that edge networks should be *forbidden* from imposing their own restrictions; thos restrictions are (usually) business-based, where backbone decisions must be more engineering-based.
