I dont see any mention of it in the current context of bluetooth device proximity tracing. It is possible, however, that apps that will build up on this API will also fetch location history separately from already established mechanisms on each OS.

As a matter of fact I see this as a very likely scenario as this is precisely what South Korea has already done.[1]

I think the real interesting private sector utility will come from implementations of the contact-tracing map instead of just the bluetooth app (which there will likely be "official" ones or ones being worked on directly by Google/Apple themselves).
