I agree with you. I am  not suggesting a separate definition of a person but
rather a location-less POI that is tied by something like image recognition
as you suggest. We are currently driving the spec to include a number of
building blocks like a location primitive which is mandatory. I think this
location-less  POI could cover a number of other scenarios like the how to
make a conference call that Jay Wright at Qualcomm mentions in his talks.
