Problem with foot=no on lawfully forbidden streets(Train-Crossing). not verifiable on the Ground

Hello, just a collection before putting it into a purposal

so there are many issues about walk=no at Gleisanlagen. Each enities pushing it to not my problem.

1. Routers need it to avoid Tracking through have traffic with separate sidewalks
2. Openstreetmap verifable on the spot
3. Historie of foot=no is changing in wikipedia.
4. StreetComplete is asking if its forbidden, not if its forbidden by sign.
5. Just use access.

Reasons:

1. “Just use a better Router”,
2. Street-Speed-Limit is also not verifable on the Ground.
3. osm.wiki/DE:Key:foot
4. https://community.openstreetmap.org/t/poll-should-streetcomplete-disable-the-are-pedestrians-forbidden-to-walk-on-this-road-without-sidewalk-here-quest-in-the-uk/118387
5. No router is picking it up

Perfect solution: https://github.com/streetcomplete/StreetComplete/issues/2472 Are pedestrians legally prohibited from walking here according to a road sign?”
