It would help 'knowing' how long ago it has been made and explain
why certain things turned incomplete/wrong overtime.<br>

So, either we warn Keymapper that they use unofficial tagging that

or I still have to learn what many people are trying to teach me:
that OSM is nothing but fuzzy (sending cars the wrong one-way) and
that the overpass query has to be extra huge.<br>

I haven't found a way to do it. You could create a union when you
