when last we saw our hero (Monday, Mar 24, 2003), Kevin Darcy was madly tapping out:Nobody's "robbing" anyone of anything. This is a matter of deprecation versus encouragement. Those who wish to deprecate end-node reverse DNS look forward to a day when reverse DNS is never used improperly as an authentication mechanism -- for spam detection or otherwise. Those who wish to encourage end-node reverse DNS apparently are comfortable with the continuation of this absurd and misleading practice.

"silent constituency"? If anyone has valid uses for reverse DNS, I
say let them speak for themselves.
why is this so difficult for folks? there are perfectly valid reasons
for having reverse DNS. if people choose to update and support rDNS
on their networks more power to them. POLA alone should be enough
reason to keep the functionality around.
i don't think that anyone here is actively promoting f-r-f checks as a
comprehensive integrity check. however, there are existing IPv4
applications, admittedly poorly crafted - which expect this behavior.
ideally, they would fix this behavior as the move to IPv6. but some
will not.
for an incremental amount of additional effort they have their IPv6 DNS world behave like their IPv4 DNS world did. what's it to you? don't rob folks of convenience based on personal views on this matter.
