Cool! I hadn't seen that. I like the idea of a solid starter kit library, although (from quickly reading the README for your starter kit) I think it should probably include more: specifically facilities for making HTTP calls, serializing/deserializing request and response data, caching data and fetch status for the requests, etc.
From working with people who haven't used Redux before - these seem to be common things people new to Redux want to do but find difficult to get started. (The boilerplate around making actions and switch statements, etc. seems a bit secondary in my opinion)
However, I realize the "proper" way to do the things I listed above is inherently pretty opinionated, so I totally understand why the Redux library itself has avoided including these things (it's much more flexible as-is; and probably why it's been so stable and stood the test of time).
