The problem is a little deeper than that, as there are people who WANT to
see a BCC: header in mail that reaches them because of BCC. One reason
being that they don't want to accidentally reveal their presence on the
message by doing a reply to all.
In the present state of things, these people clearly have to train their
senders to use some small subset of available MUAs and send from suitable
venues. (mutt and ????; sites that let the BCC through)
It will be interesting to see Philip's summary of the discussion that
develops on the ietf-822 mailing list. (My guess is that 3 or 4 "only right
way to do it" ideas appear.)
