Didn't think of that but strongly agreed.

Completely agreed and that's what I meant to say.

What I meant is that foot routes like this are found

  https://www.openstreetmap.org/directions?engine=graphhopper_foot&route=42.46043%2C-71.35108%3B42.46162%2C-71.34935

but that's a case of correct OSM data, as it should be.

I think Ticker is saying that sometimes the footpath is joined to the
amenity=parking polygon, instead of the service road, and correct
routing does not magically jump over that gap.
