generally, a relation is capable of explicitly modelling the situation, at
the cost of complicated/time consuming actions required from the mapper
(and nowadays, with a lot of mapping on mobile phones going on, average
editor relation support is even worse). Personally, I am mapping in a
context with a lot of oneway streets, so it often is not an issue to just
use a node close to the intersection, I believe if you can, you should
avoid relations because it makes the map more complex for others to
understand and modify (maybe with the exception of well supported
multipolygon relations).

The particular proposal seems thought through, but might eventually be
overengineered. In the simplest representation you would only need a via
node (at the stop line) and a from way (ending at the stop line) and be
I am not sure how several via ways should work together with several from
and to ways, and I guess even if it works, it will be complicated to
evaluate (for other mappers) and several very simple relations (only from
way and via node) would probably be much easier to understand (at the cost
of having to split the ways at the stop/via).
