HTTP 2.0 Server Push?

I'm not sure what the status of HTTP 2.0 Server Push support in express.js is actually but if it supports it shouldn't we be able to take advantage of it by pushing the assets to the client along with the prerendered HTML?

Maybe there's an obvious reason why we don't do that yet that I'm just not seeing - if so, please go ahead and close this and sorry for the noise.
