Message flags are stored only in dovecot.index files, and files get somewhat more easily corrupted than the whole filesystem. Having a separate dovecot.index.backup file helps with this though. Also there's the disadvantages if you can't easily switch away from Maildir because you're using some non-Dovecot tools to access it.
