React 18 React Architecture

With Remix and React 18 then the idea behind hydration slicing is that instead of blocking, let's say again that the hydration is supposed to take half a second, I can just break up that hydration process into 10 sections, 50 milliseconds each. That makes sense too because whatever is above the fold, unless somebody scrolls immediately which I think most people, they kind of watch it load and then start interacting. But with progressive enhancement assuming you do download the actual JavaScript and perform the hydration does not overcome that problem of hydration blocking the main thread for potentially extensive periods of time.
