So I don't think this pendulum backswing is all that surprising or interesting on its own - it's been a journey to discover the edges of the SPA paradigm's capabilities and strengths and a retreat to pragmatism mostly. What I do find quite fascinating is that React actually started out pushing this kind of server rendered, pragmatic pieced-together approach from its very first days. Indeed, because that's exactly what the facebook website required - dynamic additions to a php-like fundamentally server-rendered site. I am not sure if I'm always interpreting this correctly but a lot of blogs I read about server rendering (the buzz TLA for which is now SSR) and the general per-page approach for React apps seem to be attributing the idea of the approach to a few of the newer frameworks that have appeared. Those frameworks are great and package up a load of this goodness, but ironically you don't and have never needed any such wrapping, nor any of the learnings of the SPA era, for any of this. It came out of the box in React before it even hit major version numbers. Somehow, the idea just never seemed to catch.
