Yes - and I'd say WebSockets have been sucking the juice out of the DataCenter if your clients are mostly idling!

I'm not disagreeing with you here. Our point was that HTTP 2's features start doing amazing things after the first request, now that they have a connection going. Do read that we are excited about what it brings - just not for the very first request itself. And honestly, if they changed that, we'd be a happier lot.

Even that first request benefits from things like header compression and the more efficient encoding. The big win, however, if you are making an API client is that you can connect and immediately send all of our requests without needing to issue them sequentially. If your API design in the past has needed to prepare combined responses to reduce latency that can a pretty big win.
