If I'm right, I remember the problem of that (or a similar) labelling 
approach Microsoft made, because the buzz feature of the new system 
mentioned on the label was the Aero Look and Feel, but one label 
mentioned the new system as running, not making clear Aero was NOT 
supported - only the core system with the old-style interface.

Something like that is my fear at your approach, as long as there is no 
way to counter this issue.

well - I see that as a problem not only at OSM, but we don't have to 
make mistakes already common practise in other areas.

the Opening-hours-Map [1] made by Netzwolf uses the mapnik tiles. 
Therefore supporting all details of addresses, you can say: displaying 
housenumbers, street names, postcodes, city names and country names.

But there is no search feature, so "supports address 1.0" would be 
misleading, I think.
