I think 5322upd-from-group needs to apply to both
backward-pointing address types to be effective for what
popimap-downgrade needs.
I will make the change.
But in any case, the downgrade doc needs to remove "reply-to" from the
list of header fields that 5322upd-from-group changes. Maybe this:
OLD
This procedure may generate empty <group> elements in
"From:", "Sender:" and "Reply-To:" header fields.
[I-D.leiba-5322upd-from-group] updates [RFC5322] to allow
(empty) <group> elements in "From:", "Sender:" and
"Reply-To:" header fields.

Looks like the correct change to me.
