Indeed, we couldn't even get consensus on the much more bland statement, "Some people rely on the reverse, and you might want to take that into consideration when running your services."
The classic TCP wrapper had this as one of the security features, if reverse said something and this couldn't be verified by doing a forward lookup, the reverse was treated as invalid and not used for name based policies.
