A culvert is a type of tunnel... a motorway is a type of road. We are
talking about sub-classifications here. I don't see where this is
outside of the scope of the concept of tagging ways, let alone outside
the scope of the OSM project.
We seem to do fairly well describing the road network with a limited
subset of tags, and the road network is something that is very visible
to those of us who are not "roadway experts". Holes in the ground are
very much less observable, and therefore much harder for those of us
who are not "tunnel and underground infrastructure" experts to
identify. Without being one of those experts, it would be difficult to
know the proper tags to use. (Note, I am not attempting to mock anyone
using these titles)

Which is what I said above, even given that, it's difficult to stop a
vandal. However, someone adding roadways to the OSM database, but not
including something like a surfacetype tag is not a vandal. Even if
they tag the way as primary when it should be secondary, that is not
vandalism.

Indeed, but we can not expect every OSM contributor to be an expert on
every feature included in OSM. We leverage the knowledge level and
skill set of every contributor, from a dummy like me right up to
experts on every facet of their chosen field.
If the OSM community decides that the culvert tag is appropriate, we
simply send a bot out looking for all streams going through tunnels.
Perhaps Andy could give us a quick education on what constitutes a tunnel.
