[Tagging] Housenumber interpolation with regularlyskipped numbers

I'll have to admit that I haven't been surveying for *missing* numbers - I
have been only collecting the beginning and end of each group. A search by
address number would yield quite an accurate location. But the reverse
case, using my data in the OSM database as a postal mailing address
validator would fail. In my mind, having a navigable address would be more
useful than nothing, (or in the US, an obfuscated Tiger address).

I would add to this sites with new construction - I can generally tell
the entire area of a new subdivision addressing scheme when it is partly
complete. I can create an address interpolation way that will not be 100%
accurate because it includes empty, future houses, as well as lots that will
never contain a house for a number of reasons, however it is useful for
navigation long before the commercial companies include it. The existence
of an address interpolation way in my mind was a marker that a final survey
is needed before creating individual house number nodes.
There are plans in the US to import Tiger address interpolation
information - which is intentionally obfuscated for privacy reasons by law.
Tobias mentioned a possible tag interpolation:complete=yes to represent
fully accurate address interpolation, which sounds like a simple solution.
If it is necessary to tag estimated address interpolation differently, it
would be good to know before the Tiger address interpolation import begins.
