As chair, I can say that consensus was to make this normative, not experimental.
With the best will in the world, I was there, and I saw no such consensus.
The closest thing I can find in a quick search of the archive is this
note, which says that the group agreed on one thing (that lists should
sign their mail) but not on anything else:
http://mipassoc.org/pipermail/ietf-dkim/2010q4/014630.html
This document does not describe existing signing practice. It makes a
variety of highly speculative recommendations unsupported by experience.
It is an experiment.
