Server-Side Rendering

[dgp1130]

I recently prototyped a possible SSR implementation in rules_prerender (see the ref/ssr tag), and it worked out a lot better than I expected. We're able to easily intermix SSG and SSR on the same page and seamlessly pass data between the two contexts in a type safe manner. We can even render components concurrently and stream the result. Components can compose each other, even without knowing how a dependency divides work between SSG, SSR, and CSR.

I went into some of the details on Twitter, but I'd love to hear what the community thinks. Would this be useful? Are there improvements that could be made?

My biggest question is about how helpful it is to interleave SSG and SSR on the same page, is the performance impact noticeable? Is there a significant developer maintenance cost to the SSG / SSR distinction? Is it better than just SSR-ing the whole page?

Feel free to share your thoughts and ideas below, really interested to know if this is an idea worth pursuing.
