I don't know the number of users who use bluetooth headsets with
PulseAudio, but even just 1% regression rate can mean quite a few
unhappy users. When your headset suddenly stops working, it's not
trivial to figure out that you may need to pass a special argument to
module-bluetooth-discover in order to make it work again.

It would be better to have a module argument to enable the XQ settings.
