One more minor annoyance cleared up.
edit: after more testing, this definitely works for me to get rid of the bt volume notification, but it also seems to disable the whole top taskbar once your BT connects once. Soft reset will get back the taskbar, but as soon as you connect it will be disabled again. Just a word of warning for those of you who actually use that top taskbar (I very rarely do so no big deal).
