Do you propose that:
a) the work happen somewhere else
b) that it not happen
c) that it be split up into pieces, or
d) something else?

I feel like every iteration of the charter that I've written and the draft that 
has already been posted in this thread multiple times are really quite clear 
about the both the issues that this effort is trying to solve, and the reasons 
why they are real issues faced by many email systems out in the real world.

I'm quite concerned by the amount of "NO" energy that this effort is receiving, 
and it's a general risk with an organisation that has been around for as long 
as the IETF.  Everyone wants to have an opinion on every technology they have 
touched.  Fair enough.  But eventually everything gets mired in molasses and 
you can't progress any more.

I'm fine with "I don't want to be involved in this"... but there's real demand 
for this work.  I wish I'd arrived at the IETF before ARC was published because 
there would have been a chance to fix ARC rather than having to come back and 
do all this again.  I was too fresh to the IETF to do more than write a rant 
about how it was broken:

https://mailarchive.ietf.org/arch/msg/dmarc/4Gu1EErK4iuo9pQnZ-uJ2tKpMDQ/

But the problems that ARC didn't address are real problems, and that's why ARC 
hasn't had as rapid adoption as I expect DKIM2 (as described in 
https://datatracker.ietf.org/doc/draft-gondwana-dkim2-motivation/) to get.

And the reason I expect it to get more adoption is that it brings significantly 
more value.  It solves more of the problems that email operators are facing.  
The previous "dkim-replay" attempt didn't, which is why it didn't make 
progress, but the discussions which led to this proposal came out of that.
