I think supporting forwarding is an essential requirement for this
specification to be successful. First from a working group
perspective, part of the motivation for formation of the working group
was to better authenticate mailing lists such as those used by the
IETF. Second, when I look at Gmail data (and sharing in broad brush
strokes on this public list), I also see the need to support forwarding.
Since I never said or specified anything against that goal, this line of
purported 'criticism' is, at best, distracting. Certainly it is
irrelevant, in terms of serious technical discussion.
The assertion that, somehow, this additional (but undocumented)
requirement serves as a veto to my proposal is without any foundation.
I've asked for technical detail. So far, all that has been forthcoming
are general rejections and general assertions of need.
Technical debate requires substance.
I've shown you (some of) mine. Please show me yours.
Given the nature of what you folk are claiming, showing us yours
includes detailed technical scenario that a) shows how yours works to
satisfy the detection requirement AND how the other that has now been
introduced, and b) shows how your approach to solving the 'AND' does not
permit using the simpler and incremental approach I've offered.
By way of attempting some substance, even in the absence of your
engaging in it:
Your approach requires changing the entire email infrastructure. When
will you achieve utility at scale? Not for a (very) long time as ARC
and IPv6 demonstrate.
When will mine achieve utility? As soon as any sender and their
receivers implement it. When will they achieve it at scale? As soon as
more pairs implement it. Incrementally.
Your approach entails quite a lot of mechanism. Mine is utterly
trivial. That is not a minor difference.
Your turn.
