One particular use of the foo_link info is that all down to secondary have a
seperate position in the mapnik rendering order (painter model) - BEFORE all
non_link instances. This means that the ugly "junctions" between say a
motorway_link and a less importantly ranked road are now avoided, and they
merge properly. It used to overprint the motorway_link over the lesser one and
look wrong. So, I would encourage using the foo_link tags when merging road
types.

I'm not sure I can think of any examples in the areas I'm familiar with.
Perhaps that's just due to local road design though: link-like
structures seem to be reserved for faster, more multi-lane road designs.
Not having link roads: a concrete criterion for highway=tertiary? :-)
