James, Interpolation ways are certainly editable, and it's certainly possible to add address interpolation manually. I've started doing it here in Shawville by resurveying the streets: I just note the house numbers at the beginning and the end of each block. [1] (You can tell that I'm using OSM largely as a pretext for getting some exercise.) The nodes at the end of each way are tagged with the full address data -- addr:housenumber, addr:street, and so on. The way just connects two nodes tagged with addresses. If the node at the corner that ends an interpolation way just happens to be an amenity, well.
