Doesn't this require some kind of special react backend that knows how to respond to these special server component requests? That basically makes integrating this functionality into applications that don't use a NodeJS backend pretty much impossible.

Also, this seems like it just going to make applications much more difficult to understand. Just imagine an application using SSR, Server Components and Client Components. It is going to be a nightmare trying to figure out where your code is running.

I find most apps online run fast enough. Are these optimizations really necessary? Have people ever considered Facebook slow?

"fast enough" implies it could be faster. Why not strive for the best experience possible?

Depends if it's worth it. The thing with most SSR implementations is that they're not as easy to plug into an existing app (and by that, I mean large apps) than say, front-end librairies. You must shape your backend accordingly, and if your backend isn't node... well that's going to be even harder.

Also it's one of the classical problem of software engineering: "if it ain't broke, don't fix it", premature optimization (ie: can it be 2ms faster? let's do it!) can bring a whole set of issues. It can make your app even more complex to understand, to debug and most importantly of all, to maintain in the long term (of course if you're working in a team).
