Note that our official Redux Toolkit package [0] already uses Immer by default, and we have recommended using Immer with Redux in our Style Guide docs page [1]. (We also specifically recommend _against_ using Immutable.js in that page as well.)
Fun fact: because reducers are _just_ plain functions, there's not actually anything Redux-specific about them. That means you can use any reducer with React's `useReducer` hook as well. I've used RTK's `createSlice` function to generate strongly-TS-typed reducers for use in React components a number of times.
