Then why don't we use just 'highway=road' for any physical route that is
suitable for cars? With your reasoning highway=motorway, highway=trunk,
highway=residental, etc. are unnecessary, as the properties can be
described with other tags… But we have the another layer of abstraction
and I think it proved useful. We could define motorway by its surface,
width, number of lanes, vehicles which are allowed and which are not,
but this does not make things simple and would make interpretation of
the map very hard. Classifying ways into
motorways/primary/secondary/residental makes things simpler.
The same should be true for ways useful or dedicated for pedestrians and
cyclists.
IMHO path should be the same thing for foot/cycleways what a 'track' is
for 4-wheel vehicles. Higher-level ways should be tagged as
footway/cycleway/pedestrian.
