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 actions = [];
      for (let i = 0; i < n; i++) {
        actions.push(randomAction());
      }
      return actions;
    }
    function ContextSimulator(maxDepth) {
      const contexts = new Map(
        contextKeys.map(key => {
          const Context = React.createContext(0);
          Context.displayName = 'Context' + key;
          return [key, Context];
        }),
      );
      class ConsumerTree extends React.Component {
        shouldComponentUpdate() {
          return false;
        }
        render() {
