Link segments without link classification

[danieldegroot2]

Usually, a link road will be a connection

from a node (commonly highway=motorway_junction, in wider meaning regardless of motorway status, any 'exit' from large road)
adjacent to some way segment(s) of the larger road.

via some segment(s) highway=*_link

to another node
again adjacent to some way segment(s) of the larger road.

As in the past classifications/consensus has changed, even multiple times, some areas have been left with (parts of) link roads which are not tagged as _link. It might be possible to find at least segments which have been missed ('gaps' in link roads)

Ex. https://www.openstreetmap.org/changeset/153162642

Or look at highway=motorway_junction nodes without connecting _link -likely (nearly) none except the example though-

Though, some countries may apply different rules, as they apply different classification too.

(Perhaps something for JOSM validator if it's better or it can't be limited in Osmose)
