That’s some pretty good reasoning @pvc and @teejayess.
I’m not sure of what’s really happened here. Has Google done an Apple and created their own standard? At least it’s ‘open’ I guess, so others can play. So here’s Google, who are one of the handful of organisations at the top level of the Bluetooth Special Interest Group. The Bluetooth SIG has a Hearing Aid Working Group who are supposed to be working hard to come up with an official hearing aid profile. Google seems to have bypassed that entirely and done a deal with one hearing aid manufacturer. Where does that leave the Hearing Aid Working Group? Are we going to have two competing non-official standards? Do hearing aid companies need to take sides?
