Thanks. The wording there is:
"OpenStreetMap is a place for mapping things that are both real and
current."
Unfortunately it doesn't define "real" or "current".
No, it leaves those to the ordinary, everyday meanings of the words.
What is a "real" bus stop? Does it need a physical marker post or
shelter? Or is it a bus stop if it's just a place listed in the
timetable? Or even just a place where buses often stop on request?
What is a "current" footpath? If I mapped it 5 years ago, how often do I
have to go back and check that it is still there? If it's a public
footpath crossing a field the farmer is allowed 14 days to re-instate it
after ploughing the field. Is it still a "real" footpath for those 14
days? What if I re-visit it on the wrong day?
There are, obviously, edge cases where a decision has to be made on the
particular circumstances. Trying to define things too tightly creates
unwanted inconsistencies.
However, historic administrative boundaries, by definition, are not
current. They're not an edge case. They are completely outside the
realms of what is current.
