While updating the spec I realized it was a bit odd to provide two different ways to register StatusNotifierItems. Is there a particular reason for using a separate DBus service instead of exposing SNI objects on the application main service? Since one has to register with the watcher in both cases, I don't see the need for a separate service.

If there is no need for this separate service, I suggest switching to exposing SNI on the application service, as it is more DBus-like. We could expose them under /org/kde/StatusNotifierItem/$N to support multiple instances. If you agree I can work on a patch to do this.

This patch removes this limitation, making it possible for applications to expose an object implementing the SNI interface on their main DBus service. In other words, instead of requiring this:
