There seems to be a misunderstanding here (I just went around the block with Marcel on it). The fact is that the backend-ofono can only talk to a phone, where it emulates HFP, it can't talk to an actual headset. Meaning that if you have a headset trying to talk to your computer, you are ipso facto using the native backend. The confusion seems to be because at one time there were patches to backend-ofono to talk to headsets, but they depended on non-upstream bluez parts and they were never merged.
