createStore should perhaps accept preloadedState: PreloadedState<S> | S #3672
Description
At least as of 4.0.5, createStore accepts preloadedState: PreloadedState<S>. One imagines that one can pass S to preloadedState, and in most cases this is correct. However, there are cases in which S is not assignable to PreloadedState<S>, at least since [email protected]. See microsoft/TypeScript#35992 for more information on this issue. It's unclear to me whether microsoft/TypeScript#35992 is a typescript bug, but I'm wondering if createStore should accept preloadedState: PreloadedState<S> | S, which would mitigate the issue of branded types being mapped to never.
