This is the part that completely lost me. Why do you need an additional context for each item? Isn't one context holding all items enough?

If you have a lot of pieces of data in one React context, every component that uses any little piece of that data will re-render whenever any part of the data changes.

React has more intelligence built in than that. That's definitely not quite how it works.

React doesn't have to commit to the DOM if there are no changes, but it still has to render each component and compare the output. Even if the component is memoized, it still has to compare the props. This is fast enough most of the time but it can become a bottleneck in some cases.
