I see, you're talking about this "dovecot-keywords" file I guess

  http://wiki2.dovecot.org/MailboxFormat/Maildir

Some questions that spring to mind:

- This is clearly dovecot specific; I wonder what fraction of
  our users would benefit. I suppose that's a question about any scheme
  involving maildir-flags a-z; at least those can be synchronized ootb
  by several tools.

- Notmuch new currently only indexes one copy of a message, so two files
  in different maildirs (i.e. a list and inbox) would be pretty much a
  crapshoot which tags get applied. We intend to change this behaviour
  eventually, but no one is working on it currently.

- even if/when this behaviour changes, there is still the problem of
  reconciling different tag mappings from several maildirs.

On the other hand, maybe not much change to the notmuch core would be
needed to at least experiment with this, using e.g. hooks to
notmuch-insert and notmuch-new.
