RfC Part 3: foot_scale=* (aims to describe global paths in a more helpful and informative scale than SAC)

Mind you, it is DE:Key:mtb:scale - OpenStreetMap Wiki - While I am all but certain there is anything meaningful for me to contribute here, yet, this lately crossed my mind foot:scale. (Remember, I was arguing for foot:scale=0 - i.e. casual² - this value exists in mtb:scale :slight_smile: but the community digressed.)
