Not necessarily since they have to do with the inherently complex niche features like unified server/client rendering (e.g. RSC, streaming SSR with selective hydration, server actions).
Next.js is essentially the reference and test bed impl.
Where people go wrong is thinking they need to default to the inherently complex niche feature of client hydration which is a niche optimization enabled by a quirk of web tech.

My point is that it's fishy how they push features that just so happen to be the value proposition of the only corporation that just so happens to be able to implement them.
