I feel that 3) is the most satisfactory fix to the problem, but that at
least 1) is incorporated into the draft before it is sent to last call.
Or 4): Drop the micalg parameter. This will make one-pass processing
impossible, but I doubt that it's worth the trouble (unless the
theoretical possibility of one-pass processing is required by some
MIME standard).
The micalg parameter is a required parameter of RFC1847.
One-pass processing seems to have been a design-goal of RFC1847.
I think there are benefits deriving from the fact that openPGP/MIME is
based on RFC1847 which mean that the micalg parameter should not be
dropped.
(not least of which is that the multipart/mixed signature draft is
written in terms of multiple RFC1847 signatures, not multiple
openPGP/MIME signatures.)
