I agree we need to enabled devices that want to be tracked to have a persistent ID that allows for this. Yet, currently UUID's are discoverable by any endpoint (like a new trendy app on my children's phone) on the local network. So when we design this mechanism, let's keep in mind that certain type of devices should still be able to opt out of being tracked... (i.e. an additional mechanism that isn't purely based on hardware or stored data). My 2 cents, Stephane.
