No, but it's primarily because Meta has their own server infrastructure already. RSCs are essentially the React team trying to generalize the data fetching patterns from Meta's infrastructure into React itself so they can be used more broadly.

I wrote an extensive post and did a conference talk earlier this year recapping the overall development history and intent of RSCs, as best as I understand it from a mostly-external perspective:

So contrary to all other changes, this one was not done for Facebook to use. What was the reason behind RSC then?

Like I said above and in the post: it was an attempt to generalize the data fetching patterns developed inside of Meta and make them available to all React devs.

If you watch the various talks and articles done by the React team for the last 8 years, the general themes are around trying to improve page loading and data fetching experience.

Former React team member Dan Abramov did a whole series of posts earlier this year with differently-focused explanations of how to grok RSCs: "customizable Backend for Frontend", "avoiding unnecessary roundtrips", etc:

Conceptually, the one-liner Dan came up with that I liked is "extending React's component model to the server". It's still parent components passing props to child components, "just" spread across multiple computers.
