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.
const list = [1, 2].map(id => this.renderItem(id));
            if (this.props.reverse) {
              list.reverse();
            }
            return list;
          }
          render() {
            return (
              <Context.Provider value={{}}>
                {this.renderList()}
              </Context.Provider>
            );
          }
        }
        ReactNoop.render(<App reverse={false} />);
        expect(Scheduler).toFlushWithoutYielding();
        ReactNoop.render(<App reverse={true} />);
        expect(Scheduler).toFlushWithoutYielding();
        ReactNoop.render(<App reverse={false} />);
        expect(Scheduler).toFlushWithoutYielding();
      });

        const Context = React.createContext(0);
        const ContextConsumer = getConsumer(Context);
