I'm questioning the value of the following OAuth.State enums:

• .requestingAccessToken(Provider)
• .requestingDeviceCode(Provider)

While it can be internally useful for the OAuth client, it seems like it adds limited public value to consumers of the OAuth client and adds unecessary overhead of having to switch over more possible states that most likely will never be responded to (unless a client want to show a progress spinner or something like that?).
