There is an old saying which seems to fit here;It gets even worse. Cisco has hard-coded the list of Bogons into some of its latest low-end IOS versions as part of its "auto-secure" feature. Yes, Cisco includes warnings in the manual the user should check the official list at IANA; but I also know the power of defaults. People upgrade their IOS versions even less often then they update their Windows boxes. So we're going to see chunks of the net blocked depending on the release date of versions of IOS.
