I have added "highway=unclassified" back to way/243812354 . Because I suspect it was removed by mistake.

Bei der Kreuzung der NEA 22 und der ST 2244 bei Schneemühle sind nicht beide Straßen Einbahnstraßen in dieselbe Richtung.

Okay thank you, I have implemented the recommendations because I think they make sense. I came up with the idea of adding a swim route because I got a warning that the ladder on the swim platform is not connected to another routable object. I also haven't found any other option to map swimming routes.
