Just about every time I set up a new Context.Provider, I end up accidentally specifying a values prop rather than value. While it's a minor error, generally I build the container in which the provider resides and commit it to the code base before I ever use it. It's only later when I go to use it that I realize I did it again. Since the Context.Provider seems pretty much useless without a value prop specified, I'd love it if there was a prop error if it is missing... especially if another prop is defined on the Context.Provider instead.
