I do not support adoption of this draft as a working group document for
different reasons than I have seen expressed by others on the list.

If the Sender header field is to be used by DMARC in the manner
described in this draft, it should be an integral part of the DMARCbis
specification rather than a separate extension to it. In other words,
this should be an issue on the DMARC WG issue tracker rather than a
working group draft (and presumably eventual RFC). There are enough
different combinations of originators and receivers that might use
Sender (which the chart in Section 2 begins to describe) that we don't
need the ongoing ambiguity of whether the receiver does or does not
implement this as an extension.

I have other comments on the proposal, but will stop here as they are
not directly germane to the question of adoption.
