Exactly this.  We have received authoritative data for addresses from
government branch which gives out addresses.  If they say there is no
address for some building, than it is a known FACT, as there is no way a
building could've gotten the address any other way.

And we have satellite and plane and drone imagery which clearly shows there
is a building at that place [1], and from official database above we know it
has no address.

So we would like to tag them with noaddress=yes.  

When/if the purpose of the building becomes known later, and it is one that
has implied noaddress=yes, then we intend to remove redundant "noaddress=yes"
when changing "building=yes" to (for example) "building=garage".

[1] although aerial imegery show us that there is clearly a building, we
    can't say from them alone even what is "building:use" or "building")

Opinions above are GNU-copylefted.
