Hi,

the general OSM policy is against collections. The rationale is that there are other ways to obtain the same result (e.g. an Overpass Turbo request).

More to the point, the local policy for hiking routes is to map only those routes (or networks) that are signposted as such and/or published by official authorities. There may come a time when Sentier du Littoral is documented as a hiking route, but we are far from it.
