Correct, in general only features that map 1:1 to existing APIs are
exposed.  So that means network registration, voicecalls and call-volume
interfaces.

BRSF is supported and used internally, but the information is not
exposed over D-Bus.

Bluetooth specific features are not supported yet, these will require a
separate atom. Roughly this means anything starting with +B.. including:
	- +BINP
	- +BLDN
	- +BVRA
	- +NREC
	- +BSIR
	- +BTRH

In general the TODO list is your best source of readily available
information.  In the case of HFP HF, there is no such documentation ;)
Patches adding tasks to the TODO list to support these features are
always welcome.
