There are other commenters in the thread who believe strongly that since
the route has one name, one set of signage over the overwhelming majority
of its length, one operator, and so on, that it must be a single object in
OSM.  I'm simply arguing that as far as I can see, a case like this is
passing the data model past its limits. Maybe a superroute could unify the
foot and cycle routes? I don't know, and I really don't care all that much,
because I care more whether the software that consumes the data will
understand the situation exists in the field than whether a Platonist would
say that the foot and cycle routes are one entity or two.
