This looks like a lot of boilerplate for each API.  Is it really necessary to
repeat all of this?

Unfortunately, yes, for now. I'm working on a solution but it's trapped in C++
template purgatory at the moment.

+  static BluetoothAPI* GetForProfile(Profile* profile);

   virtual ProfileKeyedService* BuildServiceInstanceFor(
       Profile* profile) const OVERRIDE;
