But still mapping in those areas was quite normal.
Sure, quite normal… So why does this and dozens of other threads exist? (This is a rhetorical question).
Not quite sure about your message. The truck driver in the US might ask the same question, about adding a bicycle route. Is this a reason not to add bicycle routes to OSM?
I’d suggest another “civil” analogy (as bad as any analogy): some group of people came and broke the parking fence, paints bicycle markings at the road surface. In one week road service restore the parking. After couple of days parking is broken again and there is bicycle route again. And so on.
Is it worth adding such a bike route to OSM?
