Sort of.

If you enable the framework but never test positive (and thus never publish any of your keys), it's no different than if you had just kept Bluetooth on all the time.

If you enable the framework, later test positive, and choose to publish your diagnosis keys, each key can be used to link all your rolling identifiers together for the corresponding time period (nominally 24 hours). Contrast this with a randomizing Bluetooth implementation, which never intentionally reveals anything that would allow the different MAC addresses to be linked.

Of course, Bluetooth MAC address randomization itself is trivial to defeat for a reasonably capable and motivated adversary. If they can plant a bunch of radios for the purpose of tracking you, why can't they also use cameras?
