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(props.text);
    return <span prop={props.text} />;
  }
  function span(prop) {
    return {type: 'span', children: [], prop, hidden: false};
  }
  function readContext(Context, observedBits) {
    const dispatcher =
      React.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED
        .ReactCurrentDispatcher.current;
    return dispatcher.readContext(Context, observedBits);
  }
  
  
  function LegacyHiddenDiv({children, mode}) {
