that is not what I am talking about. An interface can have multiple
instances aka multiple objects can implement that said interface. That
is not what this is about. It is pretty clear that we do need this,
because otherwise the whole D-Bus model would make no sense.

My point is that the actual meaning (name) of the object path is
irrelevant and it is not needed to tie this to the interface/API
contract. And thus the namespacing of object paths becomes irrelevant.
