Signal handler for unknwon object path

[knobo]

How do I make signal handler for signals where I don't know the object path?
Like for example when ofono notifies about a new phone connected.

For now I'm going to do something like this:

(define-dbus-object mobile
  (:path "*DEFAULT HANDLER*"))

(defmethod dbus/publish::missing-handler :around ((message dbus/messages:signal-message) connection)
  (let* ((member (dbus/publish::full-member-name
                           (dbus/messages::message-interface message)
                           (dbus/messages::message-member message)))
         (signal-handlers (dbus/publish::dbus-object-signal-handlers
                            (dbus/publish::require-dbus-object 'mobile)))
         (handler (gethash member signal-handlers))
         (object (dbus/publish::require-dbus-object 'mobile)))

    (if handler
        (dbus/publish::dispatch-message message object connection)
        ;; Maybe auto generate an object and handlers at this point
        (call-next-method))))

But I hope the api could be extended to handle situations like this.

I might rewrite publish to make members and signals match (or (service interface method path) (service interface method) (service method path) (service method) (service path) (service)).

A signal will match the most specific one
So if I define a signal handler for (service), it can work as a catch all handler.
