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.
Scheduler.unstable_yieldValue('Consumer');
          return <span prop={value} />;
        }
        function ChildWithInlineRenderCallback() {
          Scheduler.unstable_yieldValue('ChildWithInlineRenderCallback');
          
          return <Consumer>{value => renderChildValue(value)}</Consumer>;
        }
        function ChildWithCachedRenderCallback() {
          Scheduler.unstable_yieldValue('ChildWithCachedRenderCallback');
          return <Consumer>{renderChildValue}</Consumer>;
        }
        class PureIndirection extends React.PureComponent {
          render() {
            Scheduler.unstable_yieldValue('PureIndirection');
            return (
              <>
                <ChildWithInlineRenderCallback />
                <ChildWithCachedRenderCallback />
              </>
            );
          }
        }
        class App extends React.Component {
          render() {
            Scheduler.unstable_yieldValue('App');
            return (
              <Context.Provider value={this.props.value}>
