According to the discussion on IRC this feature seems like a thing
many people are enthusiastically eager to have...

... but I am not -- I've been happy with the current draft handling
(yes, I had to set message-save-directory)...

... but I think I am not biased when I think that if ctrl-x ctrl-s
does something more magical than simple (save-buffer) in buffers that
looks like text editing buffer, that is going to be unexpected disturbing
functionality to someone (else like me)...

... I can easily add (and will do if this functionaly lands... :):

(put 'notmuch-message-save-draft 'disabled t)
(define-key notmuch-message-mode-map (kbd "C-x C-s") #'save-buffer)

to my $HOME/.emacs.d/notmuch-config.el

(or actually my init-notmuch.el which is in my git-clonable dotfiles so it
goes automatically everywhere; notmuch-config.el is for system-local configs)

but how are others protected?

It might be that no-one else notices nor cares (or they can handle the
situation themselves). anyway, now if this lands and we get tons of
angry responses then I can say 'I said so' >;/

PS: the brief look I had to the code I can say Mark has done pretty good
work with it.
