Personally I have no problem with tag indicating that according to survey there
is no house number for given building.

So for example building=yes representing garage would end with


And repeat for 200 nearby garage building and sheds.

And right now it is not really possible - SC will not ask address quest for building=yes,
one of main reasons is avoiding of adding noaddress=yes on sheds/garages/etc
tagged as building=yes

If it is not visible at all (building heavily reconstructed so that it
changed form) then tagging current form is OK.

- factory building completely reconstructed into apartments is building=apartments
- factory building housing museum with building shape/style/substance remaining
is building=factory (or building=industrial or...)
- apartments building used as place of worship is building=apartments
