Not much support from us on this.  We question its usefulness, as proposed.

Timo pointed out this somewhat related former proposal: https://tools.ietf.org/html/draft-neystadt-imap-status-counters-01

Maybe this makes sense if status checking is more extensible, and not limited to a single attribute?  But it also seems that this kind of solution is not something to cram into rev2 at this stage.
