Bluetooth uses MAC addresses too, so this still applies.

And no one farther than 30 feet from you will see your Bluetooth hardware address.

Yeah, but someone in your home might have a rogue phone app installed (or not even that, I bet companies like Xiaomi already so this with their smart home stuff) that scans bluetooth devices and sends the addresses so that they can be data mined.
