That means every client has Push Notifications from the start. I don't think it means what people expect it to mean (getting notified when the app is in the background or off entirely).

An interesting history: BlackBerry, the creator of Push Notifications, did sell the BlackBerry Enterprise Server that would run inside the NAT and open connections directly to phones. Outside of enterprise service, the phone has to make the connection to their server as it happens today.
first pull, then subsequently push (and when network changes, repeat).

This is like suggesting a laptop is named wrong because most of the time they're not placed on people's actual laps.
