The only time i ever used it, was when working with next.js and using redux to manage the app's states. Due to RSC's in Next.js you can't just use redux globally cos it willl render both for front end and backend components. So we create our own store (infer types(if you are using typescript) to return "configureStore()". Now we also have to create our new makeStore from makeStore. Just incase you need. Which i belileve we still don't. lol.
