Using OSM to increase use of little used public footpaths.

Hi, all.

Here in the UK, we are fortunate to have a large network of public footpaths, some of which date back many centuries. Unfortunately, due to some footpaths being poorly signposted, and underused, they are at risk of becoming massively overgrown with vegetation, or just lost because they are no longer distinguishable. My question is, is there a way that OSM could be used to indicate which footpaths are most or least heavily used, allowing the general public to use/ explore the footpaths at risk of disappearing? I’m thinking that this could be ‘game-ified’ and people could use smartphones, etc, to gain points (or some other form of recognition), for using paths, or being the first person to record a track/ trace on one.

Not sure whether this is the correct sub-forum, so I’ll post elsewhere.

Many thanks,
