I'm personally looking at this differently.  If organizations want their
Class B's split in our database knowing they may be filtered than that's
their business.  As Randy said, the organizations in question agreed to
work out the specifics so filtering wasn't suppose to be an issue for them.
I don't necessarily believe that we should (based on this one instance)
move to make a formal policy change wherin ISPs would feel compelled to
change their filtering policies....again.
