Something like road=unknown might make sense, but because the highway 
tag is used for lots of non-road things, highway=unknown could be 
talking about any kind of highway, such as a footway.  Quite a lot of 
the time you know it is a road because you drove down it, but you don't 
necessarily know what class of road it is.
