And I receive a good deal of email with friendly names like "DHL
Express" or the names of friends (who apparently have suffered address
book compromise) but completely unrelated domain names.

I phrased my comment as a question because I really don't know the
answer to this, and have been reading comments from people asserting
opinions on both sides. It would simplify the discussion if the WG could
reach rough consensus on this. And if the domain name doesn't matter,
the WG really needs to rethink the utility of DMARC.
