Yes, but RPF can be implemented in places other than the customer
edge. In those places, lack of widespread, easy, and vendor-supported
feasible-path uRPF is what I believe really hurts things.
Granted, this is along a different line than what the OP was talking

ingress filtering as much as we should?", I think it's a large factor.
