why isn't it signed any more? Has the route stopped to "exist" and they
removed the signs on purpose (but just haven't finished yet hence the signs
on the crossing roads)? I would tag "old_ref" for situations where the ref
is no longer valid, but might still provide some useful information today.
E.g. in Italy a lot of roads have passed from the national operator to the
regions (admin entities), and changed their refs accordingly (e.g. SS 4 to
SR 4), and they also put some new signs here and there, but they didn't
remove a lot of the old signs, so that you can find a lot of old refs still
signposted. In this context we have tagged also old_ref to these roads.

If on the other hand the refs are still valid, but simply aren't signposted
on some stretches anymore, I would keep them in "ref".

Cheers,
Martin
