Outdated scheduling in "Design Principles"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If that's the case, seems like this part of the docs is outdated.

Yeah, the legacy docs on scheduling aren't being updated anymore. The new docs are here as I'm sure you know. =) Might be helpful for anyone who stumble across this issue like me.
