This makes it sound like we are talking about some 
kind of network security issue. We aren't!

The fundamental issue is OPERATIONS and has to do with
policy and management of that policy. Bogon filters are
an example of a policy implementation. It should be no
surprise to anyone in operations that when technical people
implement a policy which does not actually exist within
the company, there is nobody to manage that policy
implementation and it eventually becomes orphaned.
One might argue that if a company is not capable of
setting a policy and managing that policy, then you
should not implement the policy at all.
