We've debated this many many times. I fu*kd up with the original map features list by not describing the physical and administrative aspects of a feature separately. These questions probably would not keep cropping up if I had. Anyway, my take is that we should think more of the generic tagging as representing the physical, that's what people can see on the ground and means its not necessary to think or know about the administrative aspects. This is what we do mostly anyway, its just that in the UK we conveniently tidy both up in a single tag when we do something like highway=motorway. If the byway is a track I feel it should be highway=track and then with the extra byway=true. In that way the physical and administrative are separate and easily understood. Whether we would ever want to split motorways into highway=highway and motorway=true of not I really don't know. In reality it just adds work that's not needed when we all understand what highway=motorway means.
