Checking with

area[name="Nordrhein-Westfalen"];
way(area)[highway=footway][!bicycle][oneway][oneway!=no];
out geom;

turned out that all were either mapping errors or intended to be meant for pedestrians. North Rhine-Westphalia has 22% of the German population and is thus already a quite comprehensive sample, and I happen to have seen many places there.

To make this a good rule, it should be also tested against bicycle=no in addition to the absence of bicycle. Afterwards, a pedestrian router can safely follow the rule:

  • if highway=footway is set and bicycle is absent then process it as a oneway for pedestrians
  • ignore the oneway for pedestrians in all other cases of highway=footway

or a variant that includes bicycle=no along the no bicycle tag exemption. Bonus points for looking into highway=steps. Not claimed to be solved here is highway=path or highway=pedestrian (or any other highway value), denying scope creep.
