I'll say it again: at the moment, regular people can not get a decent gpx
track of a trail out of osm unless it is pre-ordered. Single chain, sorted,
no branches, hooks or major gaps. These gpx-s are needed for navigating
apps and devices, so you can have them guide you exactly along the trail.
Nederland has numerous fixed foot trails and an ever increasing crowd walks
these trails. They are adopting the digital version of a trail guide very
rapidly, comparable to the way car navigation conquered the world.

Please have a look at Nederland on the hiking map of waymarkedtrails to get
an impression of the density of the walking trail system in the Netherlands.
