Agreed.  

Just to be clear: I am not sure I agree with those who think reverse
DNS should not be maintained, but there were strong currents in the WG
that led to the text of that I-D as it stands.  It isn't clear to me
where the I-D stands in its progression (if there is to be any) from
the WG, so I have no idea what the Chairs will say was consensus.  But
there was a WGLC in which at least some people suggested the text of
draft-ietf-dnsop-reverse-mapping-considerations-06.txt still contained
too much endorsement of the reverse tree.  My personal interpretation
of those remarks is that there will always be a hard core of operators
who regard the reverse tree as an insupportable burden (without
consideration for the v4/v6 differences).
