	/**
	 * Filters whether to load the Widgets library.
	 *
	 * Passing a falsey value to the filter will effectively short-circuit
	 * the Widgets library from loading.
	 *
	 * @since 2.8.0
	 *
	 * @param bool $wp_maybe_load_widgets Whether to load the Widgets library.
	 *                                    Default true.
	 */
	if ( ! apply_filters( 'load_default_widgets', true ) ) {
		return;
	}

	require_once( ABSPATH . WPINC . '/default-widgets.php' );

	add_action( '_admin_menu', 'wp_widgets_add_menu' );
