If the goal is to develop/discover/research methods to reduce spam then reverse
mapping of domain name system RR's is a valid approach. I don't think we need
to specify anything per se to offer that as a valid methodology (whether it's
adopted may well depend on our recommendation that it is a viable method). One
of the goals is "must not depend on universal deployment to be effective" from
the list that Paul Judge forwarded (via a link):
https://www1.ietf.org/mail-archive/working-groups/asrg/current/msg01721.html
I think the offered method fits that criteria, whether it provides an incentive
may depend on whether we agree that it can be an effective enhancement to
system operation within the context in which it is being proposed I don't think
that any proposal HAS to offer an inherent incentive (based on RFC's or
whatever) but, that is a sub-goal on the list. I think a better goal would be
'should provide an incentive for further deployment, for those doing the
deployment' because experimentation is the first step towards acceptance, we
can not skip that step if we are working towards an effectively deployed
solution.

Huh?
If there is a RFC that says "MUST" have and I don't accept emails from
servers that don't adopt I have a /lot/ less spam. And everyone
complaining I can send the URL of the RFC and say "adopt".

I doubt this is the right working group to produce an RFC that mandates
proper reverse zones. This is the IRTF instead of the IETF.
I'm starting to doubt that this is the right group to find a solution to
spam. Too many people have too many different (e.g. commercial) interests
to push "their" solution.
Depending on how you read them, there are already RFCs that say
That's the problem. Exactly what I said: "it depends" and nobody every
said "MUST". This can be changed.
3) It will reduce the costs of the abuse department, as 5000 braindead
admins with misconfigured workstations can't cause too much trouble
anymore and the complaints will become reports.
That's a tad theoretical, since it depends not only on good reverse
DNS but your new TXT RR.
No it isn't. If I have the TXT RR in DNS and I get a complaint I can
point to the URL of the RFC and say "adopt, but I will talk to our
customer about the problem".
Maybe so, but you missed the most memorable reason I've been given.
That was "not having good reverse DNS names reduces spam."
No.
