Key type safety.

[pociej]

When one go to typescript section of documentation among others can find this lines of code const uid: Key = '<user_id>' and then useSWR(uid,fetcher). It seems to provide no type safety for key, useSWR could be called by useSWR('<user_id>', fetcher) anyways.
But I could like to have type safety for the key argument. Approach to this could be something like this :

import useSWR, {Fetcher } from "swr";
type allowedSWRKey = 'key1' | 'key2'; 
const useSafeKeySwr = (allowedKey: allowedSWRKey, fetcher?: Fetcher) => {
  return useSWR(allowedKey, fetcher || null);
};

and then use customUseSwr in app.
