CreateSliceOptions.reducers is marked as required even though it is not

See original GitHub issue

I found this while writing some slices that only needed extraReducers (because they reused actions from other slices)

Here is the line where it uses a default map if options.reducers is falsy

https://github.com/reduxjs/redux-toolkit/blob/master/src/createSlice.ts#L211

Let me know if you want me to file a PR, although I don’t understand exactly why the public definition of createSlice doesn’t match the internal one and uses RestrictCaseReducerDefinitionsToMatchReducerAndPrepare

@gaspardip I just gave this a try and making reducers optional or creating a second function signature creates lots of problems in the inference of reducer types, so I’d rather not do that.

Also, I have a second thought: createSlice with just extraReducers is essentially just createReducer. Wouldn’t it make more sense to just use that instead?

Yeah. Can you file a PR to add that note to the createSlice docs page or the usage guide?
