I'm sorry, but that's an excuse, not a reason.

The application should send a proper introspection hierarchy, regardless 
of how it's written. If it's too difficult to do so using the low-level 
libdbus-1 library, maybe you should reconsider and use something easier.

We do not recommend using libdbus-1 except for very particular cases or 
developing bindings. Anything else should use a high-level binding.

And Avahi is doing just fine. It replies for all object paths with the 
same introspection -- including and especially /.

That means interface browsers simply see one single object: /.

That's fine.

I understand that there are applications that are simply not meant to be 
introspected. While toying with the idea of using D-Bus for KDE's KIO 
Slaves, they would turn out to not even reply, since those applications 
are so simple that they don't even have a mainloop. (Their whole purpose 
is to make use of blocking calls)
