I've been using "parec | pacat" as a workaround for testing, but if
the connection was done inside PA it would be at least more "user
friendly" I guess.

I think the use case of having your PC to behave as a headset for your
phone is a good example, but I'm not sure how is the BlueZ support on
this. HSP has two different roles for stream endpoints, Headset and
Audio Gateway. BlueZ implements Audio Gateway, but I haven't checked
about the Headset role.

Johan just merged it upstream and is also part of the release 4.48,
released today.
