This is an interesting idea. The lack of push updates, though, would
make it much less useful than it could be.

Here's a rough sketch of a more far-out idea: What if all browsers
were XMPP clients and stanzas could be sent to display notifications?
The attack surface would still be low, but you'd get realtime updates.
Instead of subscribing to a feed of notifications, the user accepts
what is essentially a chat invitation from the site. Like normal XMPP
invitations, this would be revocable at any time.

Lots of issues to work out, but you'd get realtime for free.
