+\r
+I see, you're talking about this "dovecot-keywords" file I guess\r
+\r
+  http://wiki2.dovecot.org/MailboxFormat/Maildir\r
+\r
+Some questions that spring to mind:\r
+\r
+- This is clearly dovecot specific; I wonder what fraction of\r
+  our users would benefit. I suppose that's a question about any scheme\r
+  involving maildir-flags a-z; at least those can be synchronized ootb\r
+  by several tools.\r
+\r
+- Notmuch new currently only indexes one copy of a message, so two files\r
+  in different maildirs (i.e. a list and inbox) would be pretty much a\r
+  crapshoot which tags get applied. We intend to change this behaviour\r
+  eventually, but no one is working on it currently.\r
+\r
+- even if/when this behaviour changes, there is still the problem of\r
+  reconciling different tag mappings from several maildirs.\r
+\r
+On the other hand, maybe not much change to the notmuch core would be\r
+needed to at least experiment with this, using e.g. hooks to\r
+notmuch-insert and notmuch-new.\r
