I always thought the whole community, including the US, was largely in agreement that addr:* tags are for mail delivery and not for describing a location. If the US community is planning to deviate from that and use addr:* more liberally, maybe it would be a good idea to discuss this in a wider circle.
I know that some people use object:* to describe that “this thing is near this address but it is not the thing that has the address” (e.g. a vending machine that sits in front of house #123 on ABC street would sometimes be tagged object:housenumber=123 and object:street=ABC street but never receive addr:* tags).
