`UseDataFunctionReturn<T>` omits properties of `T` defined as `never`

What version of Remix are you using?

1.6.5

Steps to Reproduce

I’ve put together a minimal reproduction case available here: https://codesandbox.io/s/heuristic-shockley-t1ks84?file=%2Fapp%2Froutes%2Findex.tsx

Expected Behavior

The useActionData<ActionData>() hook should contain all of the properties typed in ActionData

Actual Behavior

The useActionData<ActionData>() hook doesn’t have the properties typed as never in ActionData

@rossipedia here’s wrapper function to get typed fetchers

type TypedFetcherWithComponents<T> = Omit<FetcherWithComponents<T>, "data"> & {
  data: UseDataFunctionReturn<T> | null;
};
export function useTypedFetcher<T>(): TypedFetcherWithComponents<T> {
  return useFetcher<T>() as TypedFetcherWithComponents<T>;
}

Not sure. But note: to get the Date type, you have to use the superjson helper. Otherwise, you’ll get the JSON serialized type. So in that screenshot, it will be today: string if you’re using standard json on v1.6.5+
