The dev here- there are exactly 2 features- Head Gestures and heart rate monitoring. Both have no use on Linux. On Android head gestures is to answer calls and heart rate will be provided to Health Platform.
edit: there's just one that's not planned for Linux and planned for Andorid- HRM. Head gestures is already implemented on Android.
Is there a reason head gestures couldn't be mapped to functions in Linux? I see little reason why you couldn't have it used to play/pause or something. Heart rate monitoring less-so... but even that exposure could be useful for something if given the right API.
