The AirPods already work outside of the Apple ecosystem. This is just someone building out interfaces for their extra features that are already integrated into Apple operating systems.

Yeah I understand. But there are plenty of good headphones that work with Android and include most of the features. That's kind of the point of Librepods right? To bring AirPods up to par for non-Apple devices and make them a viable option for Android and/or non-Mac users. So "this working" means those features.
