I think I like this approach: I think we will like the freedom to tweak
message-mode.

These both seem good. At the moment notmuch-fcc-header-setup checks
whether the fcc directory is a valid maildir. This used to be called on
sending but is now called when the message composition is started. I
think it would be better to move it into notmuch-mua-send-and-exit or
(perhaps better) in notmuch-fcc-handler itself (in case the user edits
it).

Do you mean the buffer name is *mail*? We could just call rename-buffer
somewhere (maybe in our derived mode bit?)

This is a little irritating in case people have customised key bindings
but I don't see a way round it. 

A related case, which we probably should fix, is that C-c C-s is bound to
message send (and don't exit), this probably needs a wrapper too.
