I would be really surprised if AndroidWear would only use Profiles
specced by the Bluetooth SIG. AFAICS there is not too much except the
notification and heart rate stuff in the standard. All the goodies like
watchapp/watchface management and even things like step counter, sleep
monitors etc are not part of the Bluetooth spec and so it has to be
something custom or at least something not standardized yet.

I agree Pebble could've at least used AVRCP for music playback control.
But apart from that, not too much useful stuff in the GATT spec (yet).
