Yeah but that's not just a React issue. It's even worse for Angular, but Vue's transition from v2 to v3 was pretty smooth because of backward compatibility. Svelte has no supported way to create a SPA anymore, you'd have to use Vite for that. It's SSR like next.js. Terrible.

But Angular is the worst in terms of backward compatibility and it has the worst state management too. It's like they took everything bad from React and made it a standard.
