I see your point, but my usage is that I have INBOX, where mail that (in
theory) I want to see quickly (also on phone) arrives, and many other
mailboxes for things that I want to look at with much higher latency.

Right now I have a mail-notification widget in the status tray that
tells me if INBOX has unread messages.  But it would be nice if the
unread count in INBOX automatically reflected what was happening in
IMAP, so that I could see the 1 from the arrived message and just hit
space to enter INBOX without typing g.  I would only want gnus to IDLE
on a tiny number of mailboxes, probably just 1.

But I don't want this badly enought to write it - just trying to explain
why it would make sense.
