Do you think that GPS coordinates will be exposable with the API so that there can be public tracing maps online? Obviously a big privacy issue where the actual bluetooth ID and the person's identity have to be fully anonymized but if GPS coordinates of contact points can be exposed publicly, there can be good public tracing maps that can show where contact events are happening and in what numbers so that people can avoid certain areas (and on the other end where other areas are safe where there's no contact). This can publicly also be used to display R0 counts in different zip codes and geographic areas.
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).
Just to clarify, the Apple/Google proposal discussed here does not require geo location (and I’d assume that you don’t have to give it access to location data).
