Outdated scheduling in "Design Principles"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If that's the case, seems like this part of the docs is outdated.

「Design Principles」のドキュメントページを見つけ、引用されているスケジューリングに関する箇所を、リンクされているReactのissueとコメントと併せて確認してください。記述が古くなっているかどうかを確認し、その後、影響を受ける文言をReactの現在の更新スケジューリング動作に一致するように修正し、ドキュメントの変更を検証してください。
