El Camino Del Rey is currently actually classed as a via ferrata. I think it would be appropriate to maintain it as one, as the Italians do with theirs, but if it was restored to original condition, it would no longer be a VF - it would be a path. As a via Ferrara it's utterly iconic. As a path it would be impressive, but I fear, sanitised. I'm aware it would give more people the chance to experience it though.
