Ciao pygmy nick
Adding ";path" after "highway=track" doesn't add these paths to the "Walker's Haute Route" (https://www.openstreetmap.org/relation/3020521) but makes the track/path *not* render on OpenStreetMap anymore.
And since all the tracks were already members of the route and a hiking route can happily include highway=track https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrack I modified your changes in https://www.openstreetmap.org/changeset/165928895

Happy mapping,

PS: I'm looking at "weird" higway-Tags in Switzerland, that's why I'm here...
