I would disagree, the data differentiates what type of routing can be developed. The renderer should not be a consideration per https://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer. I would also point out that both https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtraffic_signals and https://wiki.openstreetmap.org/wiki/Tag:highway%3Dstop are de facto due to practice. Where intersections include pedestrian crossing or possible pedestrian interaction the stop point is more valuable for routing and analysis.
