I think you're playing with semantics in a way that makes sense to you, but not necessarily to others. These "conventions" have been established so long (the "no entry" sign was internationally adopted in 1931), and are so widely understood to have one single meaning, that there is no longer any question of interpretation. There are objects present on the ground, of a certain appearance. That dictates that we enter certain tags into OSM, associated with a geometry which reflects the position of those objects. That's all there is to it. That is fundamentally how OSM works. Observe geographic fact; enter fact into database in way agreed by community. > And highway value is certainly not geographic.

In the UK, it's exactly the same situation as a one-way street. Where there is a road with green signs, with a number in yellow beginning "A", we tag it highway=trunk. Where there is a road with white signs, with a number in black beginning "A", we tag it highway=primary. And so on. I realise that other countries have different conventions that may not be so closely tied to signs, but they should always be tied to observable facts.
