Door location is how you can tell if a house is in the Netherlands or in Belgium, for Baarle-Nassau/Baarle-Hertog. Move the door and you move countries.
Outline is not time invariant. If I turn a duplex into a single family, or build out, then the shape changes. If I live in Coober Pedy and build out underground, then do I use the surface outline or the underground outline?
If I relocate the house a few meters away, the address definitely changes.
Really, this is best for the billions of people who have no address. Most likely it will boot-strap, so in 100 years the name "X.Y.Z" will refer to the ghost of the place that once was, but everybody local knows what it now means, as will the databases. With a layer of apt. #1, #2, etc. on top of that.
