Thank you for your reply.

I see what you mean, how changing the FCC would prevent the ability to
manually edit the FCC.  But what about updating the FCC when the
"From" changes?

When starting a new message, and assuming that there is more that one
possible "From", the default "From" will often be wrong.  I would also
expect one to set the "From" before any manual changes to "FCC".  If
so, then I think it could make sense to update the "FCC" when the
"From" changes since there would be no manual adjustment to FCC lost.

You mention updating the "From" when the "To" changes with the
notmuch-address-post-completion-functions hook.  Could there be a hook
for when the "From" changes which I could use to change the FCC?

This message-templ seems ideal for another issue of mine.  I will look
more into it.

Thank you
