okay, then we might need an extra way to tell them apart. Especially
since via D-Bus could modify them later on. And it would be nice to know
if these changes are stored back to the configuration file or not.

I can try to break your new code if you like :)

I was doing a lot of GetAll calls on various interfaces. And actually
never restarting wpa_supplicant. So over time this could have been
accumulated into being noticeable. I am currently just looking for the
behavior and correctness of the new D-Bus interface.
