The advantage would be an external mechanism would more easily be able
to syncronize two separate mailstores without going through the IMAP
interface.  Apparently this advantage isn't great enough to overcome
the lower performance of an IMAP daemon having to suck metadata out
of each of those files, verses just reading the index.  And presumably
a Maildir based IMAP would have to resyncronize message ID numbers
each time, unless it stored that number in the file.
