I've replied to all these in previous mails.

We do disagree on this. I don't think Bluetooth headsets should be
used as general-purpose capture devices. If a user really wants to do
so, there is a mechanism to allow a manual switch. Most users will not
be using this and do not need this.

I think we've gone through the previous arguments multiple times, and
disagree on the last point.

Unless someone else wants to chime in with a good reason to support
this mechanism, this is a NAK from me.

I'll probably write another patch to have the media-role work merged
into module-bluetooth-policy at some point, unless someone else wants
to take it up sooner.
