I don't think they're a problem either and I also backup a maildir-based
mail server.
However, one thing you may want to be aware of - unless you take
specific steps to avoid it, the maildirs on tape won't necessarily be in
a consistent state. Obviously this won't affect your IMAP server - but
it does mean that when you restore, metadata like whether or not emails
have been read or replied to and recently received/sent email won't be a
perfect snapshot of how the mailserver looked at any given point in time.
