I get the impression that React is trying hard to catch up with the more modern, easier, faster and cheaper alternatives. But instead of fixing the root problems (rerendering and often required memoization, leaky abstractions) and make React easier, it becomes more complex.
If the end result was great, I would understand all the effort. But it isn't. React is even slower in real world than the benchmarks show. Next is even worth. I've seen recently many dog slow websites built with Next.
Really, I don't get. If the React team wants to improve React they should fix the core.
