The examples in my previous message are from 30 km/h zones in
Switzerland, where there are no marked or signalised pedestrian
crossings except near schools or homes for senior or handicapped
people and where pedestrians therefore are allowed to cross the road
everywhere. The general rule here is that pedestrians must use a
designated pedestrian crossing, underpass or bridge if there is one
within 50 m.  As far as i know, the situation is similar in other
countries that follow the Vienna Convention on Road Signs and Signals,
except that the distance varies (often being 100 m).

That's exactly the big problem with sidewalks being mapped as separate
ways in areas where there are no or few designated pedestrian
crossings and where it is allowed to cross the road everywhere. Even
when, at intersections, you map unmarked crossings that are logical
continuations of the sidewalks (which are more or less verifiable
because used by many people) (example ), you still get unnatural
routes that are long detours (example ). At least in these areas,
mapping sidewalks (and pedestrian lanes) with separate ways seems more
problematical than tagging them on the street way.
