We disable notifications for some technical folders (huge volume and
uninteresting for our case).
I don't know if it makes sense to disable notifications for user's
folders too, since those notifications are not intented to the end
user (not directly)
otherwise IMAP METADATA could be used to turn off notification

I agree. The cost to get the data and send the notification is
insignificant. By default notifications are send for all folders.
I will try to promote this view in-house :)
