Sure, it could be. On the Finnish OSM forum there was a recent
discussion how to tag cycleway underpasses. The tunnel=yes tagged ways
under highways sometimes are roads under bridges, and sometimes
something that could be considered a tunnel (narrow walls) by a liberal
definition of tunnel. "Real" tunnels are much longer than they are wide,
aren't they?
I would rather omit these "useless" tunnels from the map display, at
least as long as one can't easily select which layers to display on the
map. There are many access=private tunnels under cities that the general
public is not aware of: wastewater treatment, access tunnels to railway
tunnels, tunnels for emergency vehicles, you name it. It would be
confusing to see them as ways on the map. That's why I hid the
underground railways in the default style.
