  // Stream wrappers may be provided by contrib modules, e.g. Flysystem.
  // In the case of modules, there is no API to determine and dynamically add
  // the module dependency. If Drupal is installed from configuration, this
  // could result in CDN rejecting the saved config which references a stream
  // wrapper from a not-yet-installed module.

    return;
  }

      // Rendered output that is cached. (HTML containing URLs.)
      'rendered',
    ]);
