Let QHttpServerRouterRule accept variadic arguments?

Right now we must have 1 <arg> for 1 argument in path pattern so that handler can parse it correctly. For exampe,

httpServer.route("/query/<arg>", [] (const QHttpServerRequest &request) {
        return host(request) + u"/query/"_s;
    });

only matchs single argument, e.g. server.port/query/1. I don't think there is a way to have variadic argument in URL, e.g. server.port/query/1/2/3/as_many_as_needed/..., right now. So maybe implement such functionality in some future release?
