It reached a conclusion quite a long time ago. The argument was about what to tag the waterway with to indicate that there is a culvert. I don't think there has ever been a push to tag the highway to indicate that there is a culvert.
We need to model/tag the culvert as part of the road infrastructure.
Are you sure about that? As Phil points out you can spit the way above the culvert and tag that with maxweight, width, maxwidth, or whatever to indicate the effect that the culvert has on the traffic that is allowed to pass over it.
OSM doesn't really have any existing tagging for flood vulnerability of water crossing, except perhaps bridge=low_water_crossing. ford=yes could be anything from a track over a watercourse that runs maybe once a decade to a crossing that's only safe to use for a couple of days a year by vehicles equipped with a snorkel.
