<?php
$statusRoute  = $routeStack->getRoute('status');
$versionRoute = new Segment('/v:version');
$chainRoute   = new Chain(array($versionRoute, $statusRoute), $routeStack->getRoutePluginManager(), null);

$routeStack->removeRoute('status'); // Not really required, as addRoute() will override this anyway… just for completeness. 
$routeStack->addRoute('status', $chainRoute);
