> only the Bluetooth MAC address of the target devices has to be known

Android has a feature of "Bluetooth scanning" to improve device location (similar to Wifi scanning). I'm not sure, but even if Bluetooth is disabled in the menu, this might still activate Bluetooth occasionally and perhaps reveal the Bluetooth MAC to the (nearby) world?

IIRC that doesn't enable BT if disabled, only uses it if available.

It says "Bluetooth scanning — Let apps use Bluetooth for more accurate location detection, even when Bluetooth is off." I doubt it makes the device discoverable though.
