I think big question is to ask oneself is “What it the actual purpose of footway=*
tag, how is it being used, and how certain tagging of those stubs adds or substracts from that purpose?”
- I personally wouldn’t add a
footway=*
tag at all unless it was unambiguous (and, as this thread shows, it is ambiguous). - if something is to be tagged,
footway=link
would fit, but is (too) generic. footway=traffic_island
might technically fit, but people usually won’t call it traffic island if it is not in the middle of the road, but at its side.- Ideal would be separate value that reduces ambiguity (Taginfo shows few undocumented values which might be that e.g. footway=crossing_access).
