Perhaps that's how OSM has defined it, but if so they have misdefined
interpolations in a way that makes them useless. If you know where
all the individual houses are, why bother with an interpolation?
What is one supposed to do if the number of houses is unknown? Do I
need to propose an
to handle that situation?
