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.

Cheers
