Unable to answer "What’s the surface here?" – Foot Path – https://osm.org/way/870859740 via StreetComplete 58.2:

This is not a path, it is a steep 2 meter height gradient between higher and lower ground levels. This area used to be a slope before the sport fields were made. Confusion is understandable if someone drew this based on a satelite photo, but nobody on the ground could mistake this mini-cliff for a path.
