I don’t think IMAP is a good example here. Your email client will try both subscribing and classic polling. Subscribing is not a MUST. And from the point of view of end user, the difference when polling in a classical way is simply that the user will be notified later, so it’s hard to tell what the client really did in the background.

I receive emails instantly. There is polling option in settings, I've disabled it.
