Maybe? 

Is the shared “central agent” the same as  or part of the “same user agent”? Is it a push server? A shared session with the push server (i.e. a shared push client as part of the UA)?

To broaden the question: Is this “central agent” on the usual architecture picture for webpush, or is it something different?
