It's pretty common in the voice world to want to announce "You have 4 new
messages and 384 saved messages" without ever FETCHing the saved ones.  Our
mail server has a proprietary extension rather like the status counters for
this purpose.

Yes.

IIRC, the STATUS-COUNTERS extension could have helped you do this. It's 
one of the things from the VPIM people. I don't know what its status is 
- the draft is expired. Its name used to be 
draft-neystadt-imap-status-counters.

How often do you want to JUST count the messages? I suspect that mostly, 
the client will want to do more, so this waste ought to be very 
unusual. There's other waste that occurs much more commonly ;)
