I wouldn't trust it.  IIRC, it was added years ago and given the  
syntax changes to the SELECT/EXAMINE call since then (e.g. QRESYNC  
extentsion), it is doubtful the code has been updated to handle these  
situations.  And in a server-caching IMAP server like dovecot, all  
that SELECT information is not expensive anyway, so any gains would be  
miniscule.
