Something that comes for free with Redux and its abstractions like Kea (the approach promoted in the linked blog post) is that you mostly avoid the problem of needless re-renders.

Each `useSelector` call (and `useValues` call that uses it) triggers a re-render only when the value changed. So unless you have something forcefully re-rendering the root node, only the few relevant sub-sections of the page will re-render.

It's not perfect nested-sub-object level precision, but in practice works well enough.
