You *do* do ingress and egress filtering of your own addresses, and have checked that your router does in fact use cryptographically challenging seuquence numbers, right? And even if you don't, using MD5 is not *that* expensive (or shouldn't be), and provides security in depth. Unfortunately, I'll bet there's a LOT of routers that don't have filtering in place, don't have good sequence numbers, and don't use MD5.
