Pretty sure the idea is to replace the current system's functionality.
I'm not sure if that means update_notification will go away or not,
but from what I gather on the expected use cases it'll be a "new code
should use comet" type of situation. As far as estimates, I'm not
sure. I don't have too much knowledge on the current status, just that
there was work being done on some necessary bits. Keep an eye on dev@
and you'll be up to date as things start building up.

If you mean in trunk, I'm not sure but I doubt it. If for no other
reason than if we added such a feature to trunk it'd be a signal that
we intend to support it for a very long time when we're already acting
on plans to replace it.
