Comparing it to the alternative of health professionals doing contact tracing, in addition to the fact that it's vastly better at its job, it would also be a privacy-protecting system. Say that I have close contact with a co-worker named Joe on a regular basis. I get diagnosed positive. I don't have Joe's phone (it's not all that normal to exchange personal phone numbers with co-workers). So now I'm asking sick time from my manager John and talking with someone performing contact tracing. Now this health professional has to play phone tag to get Joe's number, and John will obviously put 2-and-2 together and know what happened. So will others in the phone tag.
