Apple, like every other vendor, does not have a choice but to implement this as a proprietary characteristic. Pre-BLE, other vendors copied Apple's de-facto `HFP AT+IPHONEACCEV` standard for reporting battery levels to the OS.
They could publish the details, and not block other manufacturer details, so that it is easier for other platforms to develop drivers for them. Or develop a new standard that works for their earbuds.
companies actually can build and ship stuff that isn't inter-operable with the world, this is Actually Good for user experience
- Multi-device Connectivity
- Accessibility Settings and Hearing Aid
While the following are exclusive to Apple devices for market reasons:
- Receive Battery Information
- Set/Receive ANC Modes
- Set Adaptive Audio Noise settings
- Receive In-Ear detection Status
- Personalized Volume (use at your own risk - might randomly boost volume to some high level)
- Conversational Awareness
- Ear Detection
- Siri (Voice assistant on long stem press)
- Hold and Press configuration
- Head Tracking (for Spatial Audio and Head Gestures)
- Rename AirPods

I imagine limiting such features to Apple devices is more about incentivizing the Apple Ecosystem than quality or software concerns
As a neurodivergent person I lack the innate human skill to filter voices out of a cacaphony of noise so loud bars etc are hell. There also the "talking with earphones in is rude" but that's an issue that can just be explained.
Needing root to enable it is a major deal-breaker though :( and moving to an iPhone is impossible for me. Too much stuff that's not supported.
They have a basic app for some of their other devices like the Beats line. One other thing you simply can't do without pairing AirPods with an Apple device is enrol them in AppleCare One.
Care to offer a justification for why this is the case without resorting to "the multi-trillion-dollar behemoth can't be bothered to build an app"?
