The more we move "policy" information or in this case Jim's reputation-based
policy r= idea to the DKIM policy record, the better, where it ought to be
to better cover the legacy transactions (those without signatures).

errataafter the consensus call
I'm not sure what my opinion is on that last point, but on the first
point I think it's best to define an identifier that's specifically
for ADSP's use, if we want that function. Some signers may give that
tag the same value they give i=, and there's no harm done. Some
signers may use a different value, which would demonstrate the wisdom
of separating them.
Seems like a reasonable way to avoid the i= fight. If there's
I can whip up a new ADSP draft with an r= tag.
I view introducing a new tag at this point as problematic.
Using i= or even going to using d= does not require any changes to
current DKIM signing implementations. Introducing a new tag means that
implementers are at the mercy of the timeframes that vendors choose to
change how they sign DKIM.
As I have said before, I can personally accept using d= because of how
we chose to implement DKIM signing for our domains. I lean towards i=
for ADSP because I believe it gives others benefits.
