Outdated scheduling in "Design Principles"

This is a subtle distinction but a powerful one. Since you don’t call that component function but let React call it, it means React has the power to delay calling it if necessary. In its current implementation React walks the tree recursively and calls render functions of the whole updated tree during a single tick. However in the future it might start delaying some updates to avoid dropping frames.

If something is offscreen, we can delay any logic related to it. ... To be clear, we are not taking advantage of this right now.

As far as I understand, React is taking advantage of delaying updates? https://github.com/facebook/react/issues/6170#issuecomment-318204454
If that's the case, seems like this part of the docs is outdated.

Trova la pagina della documentazione “Design Principles” e rivedi i passaggi citati sulla pianificazione insieme all’issue e al commento di React collegati. Conferma se le affermazioni sono obsolete, quindi modifica la formulazione interessata in modo che corrisponda al comportamento attuale di React nella pianificazione degli aggiornamenti e verifica le modifiche alla documentazione.
