That tag I mentioned would only make sense if the addr:interpolation
tag's definition didn't already assume completeness. Apparently,
however, the tag description is based on that assumption.
We can therefore
1) change the definition of addr:interpolation
2) define a way to enter estimated/incomplete interpolation.
Cleanly changing a definition, however, isn't actually possible in OSM
(in order to do this, we would need an authority to make the decision,
inform mappers and run bot to change existing tags to match the new
definition), so we probably need to do 2).
The way to enter incomplete interpolation info could resemble the
Karlsruhe schema (incomplete_interpolation=* or whatever) or it could be
combined with a dedicated TIGER addressing scheme as Anthony suggests. I
don't know anything about TIGER's address data though, so I can't tell
whether that's a good idea.
