+   * Note: The use of this wrapper in particular is especially discourged. Most

+   * modification or wrapping when run from a command line tool, from certain
+   * queue processors, or from automated tests.
+   *
+   * If code must access the request, it is considerably better to register
+   * an object with the Service Container and give it a setRequest() method
+   * that is configured to run when the service is created.  That way, the
+   * correct request object can always be provided by the container and the
+   * service can still be unit tested.
+   *
+   * If this method must be used, never save the request object that is
+   * returned.  Doing so may lead to inconsistencies as the request object is
+   * volatile and may change at various times, such as during a subrequest.
