It does seem like someone is adding incorrect refs based on a
misunderstanding, and it would be good to have that resolved.  People
with strong opinions doing wrong things and the db ending up that way is
an unfortunate part of OSM, but comes with the good parts of evolving
tagging.

That's a good point.  At Boston's Logan airport, there are a vast number
of connecting roads which are sort of like link, and they have refs,
with signs with letters on concrete barriers.  I am pretty sure the
purpose is not for motorists, but for fire/police etc. to be able to
locate specific places where help is needed.  I don't know if these are
tagged, but if so and a router is confused, that's a router bug.
