I'm not surprised in any regard.  There are too many names for BCP-38, SAV, SSAC-004, BCP-84, Ingress Filtering, etc..

There are many networks that perform this best practice either by "default" through NAT/firewalls or by explicit 
configuration of the devices.

There are many networks that one will never be able to measure nor audit as well, but that doesn't mean we shouldn't 
continue to work on tracking back spoofed packets and reporting the attacks, and securing devices.
