We started a greenfield project a few months ago and decided not use Redux and try the context API instead. In retrospect, that was a bad idea. Context is fine for a small app, but small apps tend not to stay small... and then you're stuck with the Yugo when you what you really need is a truck.

In our main app we also use advanced features like what Slack is describing in their post, like having multiple Redux stores. We also combine stores from multiple sources (e.g. appStore = [...store1, ...store2, ...storeFromALibrary]. It's incredibly flexible.
