As I understand it, there is an implied direction in that the convention
is that the give_way node applies to the nearest intersection involving
the way. But yes, I can see that involves extra computation.

The trouble with nodes is that they are non-directional. Junctions in
quick succession, and lane-dependent give-ways could make a
challenging scenario for a program to try and make sense of. Why not
tag it explicitly instead of leaving it to heuristics which (by
definition) will not always get it right?

In the UK (particularly in rural areas) it is common to find a road
that turns 90 degrees to the left or right without a junction (that
is the road just continues and white lines mark it as such).
Meanwhile another road may come in from the other side with a 'give
way' style junction.
One simple way of representing this situation is to place give_way nodes on the
subsidiary roads. Whether any routers or renderers make use of these to deduce
that a particular route through the junction is the 'through route', I don't
know.
