We discussed pushes without a request as context in h2, and concluded that they were very difficult.  Using the request as context is what made it possible to support push at all in cases where there are multiple users of the same connection (a common occurrence).

I can see how using 0.5 RTT for pushing some content is appealing, such as origin policy, favicons, or other such common resources.  However, I see that as an entirely new feature.
