Oh, I didn't mean to focus the discussion on angularjs; that "angularjs" that I was using was essentially a totally different and now-deprecated framework from today's angular. I just meant it as an example of why I don't see this as an up-and-coming idea, but rather something that has been the clear best path for a very long time, but doesn't seem to have taken off.

I don't know enough about any of the frameworks you mentioned to evaluate whether the "hybrid in some capacity" actually does mean this approach has become widely used, but I guess from my experience of using the web, it doesn't seem like it is common, it seems like most applications are still sending a skeleton and then filling the data in client-side, rather than rendering the initial page load server-side.
