Yes, I am already considering it, but it has various limitations, which I would like to avoid.

Windows is indeed a different beast, which is why I am looking for contributors. For Linux it can be done, but since I don’t have a macOS based device, I cannot work on a macOS based implementation.

You have quite an interesting situation here. You could use a good Bluetooth adapter, pair all your devices to it, and maybe use pulseaudio/pipewire (depending on what your system uses) to manage audio inputs/outputs?
