Turning off rDNS is equally likely to create an operation impact for someone else as it is for the offending party, therefore penalizing the wrong party. Using rDNS as an enforcement mechanism is likely to have unintended consequences.

Yes, I realize revocation has a large impact and that it is a feature in 
this case.  So in the case of revocation when I as third party runs into 
an issue with rDNS for an address, they do a Whois look-up and find the 
allocation is no longer valid, stop, done, over, move to next trouble 
ticket, it is an invalid assignment.

If ARIN removes rDNS for an allocation but doesn't revoke the 
allocation, removed the Whois entry, how as a third party do I have any 
clue what is going on?  This is what I'm objecting to in using rDNS as a 
leverage to gain compliance.  As proposed rDNS will stop working and 
third parties will not be able to determine why.  This create a 
potentially larger impact on third parties then actual revocation.

The only way I can see a proposal like this working is to add some kind 
of status field into Whois, with a status like "suspended" in this case. 
  I suspect the status would be more or less ignored, but at least a 
third party can find a clue to the cause of the rDNS disruption created 
by this proposal.  Without some kind of published status change, or a 
full revocation, the confusion created for third parties by a proposal 
like creates an unacceptable impact, potentially larger than full 
revocation of the resources in question.
