ColorSchemeName types are incompatible #358

It's a generic question in the repo I see ColorSchemeName type defined as
type ColorSchemeName = 'light' | 'dark' | 'unspecified';

https://github.com/facebook/react-native/blob/17cba6e1aff4e5839a6a2891fac0e4994073b8cd/packages/react-native/Libraries/Utilities/Appearance.d.ts#L12

Question is shouldn't this be 'null' instead of 'unspecified'.
