Before we had one hierarchy where everything was a component, logic and visuals.

Now we have two hierarchies where visuals are components and logic are hooks.

One one hand, staying within the world of React components gives you a lot of functionality for free. And with Suspense and Hooks, the amount you can do within a component has become even greater.

On the other hand, there are still things that you can't do within a component. For example, you can't easily run an async function once when the component mounts - which in my opinion, would be the perfect way to fetch data.

I've been building Navi to try and create a more natural way to map routes to views and a stream of data. The thing is, the more edge cases you cover, the closer it becomes to just building React from scratch.

At this point I still think that routing and data fetching is better handled externally from React, but it's less clear cut than it used to be.
