I googled a bit and saw something about hard links being supported but
only within a directory. Or maybe that was about symlinks.

I recently changed maildir link() calls to rename()s, mostly for OSX.
There's still one link() call where dovecot.index.log is linked to
dovecot.index.log.2 file.

Dovecot has the same problem with dovecot-uidlist file too. You can move
that elsewhere too with :CONTROL=/somewhere.

Have you looked at http://dovecot.org/patches/quota-rewrite.diff? I
think that could be a bit easier to understand.
