Given that the exchanges were on an open mailing list, I'm not quite 
sure what that means.

What I am sure of is that I've pressed quite vigorously and repeatedly, 
first on the open dmarc.org mailing list and then on the IETF DMARC 
mailing list, for folk to cite work that needed to be done and to 
develop group support for that work.

What I saw was some individuals suggesting some bits of work, but no 
support developed around it.  (By 'support' I mean more than a few folk.)

Perhaps you can point to specific examples of this 'shouting down' 
happening?

What I also saw was some folk insisting that the charter be vague and 
unconstrained, with no concern for the installed base.

Changes to the core of a protocol is the essence of de-stabilizing its 
installed base.

Writing a charter that permits de-stabilizing a substantial installed 
base only makes sense when there is a clear and compelling basis already 
known for needing to make such changes.

With respect to DMARC, none has been offered or has developed community 
support.

Writing a charter that permits de-stablilizing an installed base 
covering 60% of the world's email traffic, in the absence of a clear and 
compelling understanding of the need would be irresponsible.

Arguably, the mere existence of such a charter would be de-stabilizing, 
since it means that anyone considering adoption has an excuse to defer 
it to the indefinite future, when the IETF might get around to releasing 
a revision.
