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.
return (
            <Context.Provider value={{foo: props.foo, bar: props.bar}}>
              {props.children}
            </Context.Provider>
          );
        }
        function Foo(props) {
          return (
            <Consumer unstable_observedBits={0b01}>
              {value => {
                Scheduler.unstable_yieldValue('Foo');
                return (
                  <>
                    <span prop={'Foo: ' + value.foo} />
                    {props.children && props.children()}
                  </>
                );
              }}
            </Consumer>
          );
        }
        function Bar(props) {
