Hmm. I'm not totally sure about the differences between HF and AG so 
take this with a grain of salt, but...

It seems to me that it's not extremely unlikely that either of us will 
step into the other domain in the future, i e, bluez 5 might implement 
AG audio or PulseAudio might implement a native support for HF.

Also, if the AG plugin of Bluez 5 supports RFCOMM/AT commands then we're 
already partially overlapping, because that's what we use to set/get 
headset volume and mic gain. If we enable both backends, will that then 
send AT commands from both backends when we try to set the volume, or...?

Hence, instead of removing all backend switching code, maybe we should 
instead add a switching mode "both" which does what you say. Or 
potentially replace "auto" with "both", if "auto" now makes no sense.

Finally, I remember Arun had a strong preference for not enabling the 
ofono backend by default, so Arun, could you elaborate upon whether that 
still makes sense given this new information?
