[ncc-services-wg] spurious(?) revDNS lameness alerts?

Dear colleagues, has anyone (other than myself) received an alert message from the NCC regarding "lameness" of revDNS zones for IPv4 and IPv6 PA allocations? At first glance the alerts seem not to be justified, at least not as seen from my end. Thanks for any feedback, on-list or private, Wilfried.
