Though the design problem being solved was mostly "The UK has Sustrans and MOT routes and existing ref=* can't deal with both", not that "EU routes also cross through the UK" and "the US has three national networks, at least 70 state networks, over 200 indian networks, and nearly 4000 county networks for highways, not counting the potential for nearly the same number of the same for cyclists". Not a problem yet but wouldn't surprise me, especially now that a lot of places are moving bicycle infrastructure from "nice to have if we have money left over" to "no hurry, 20 years ago is fine" thanks to COVID19, that we might need to make route=bicycle relations have the same network=* tags as route=road, down the line. > I explained this to some city planners, newer to OSM than I was, with > three examples (an Interstate that actually includes a Ferry, clearly not > part of a single paved way, a bus route traversing many different streets, > and the MRT (Miss.

But yeah, routes are frequently highway=* agnostic within the limits of the type of vehicle that the route is intended for, for the most part (granted, Historic Route 66 has at least one staircase in it now).
