Is there anything wrong with that?

>>> what I wrote was that - according to some technical definitions - a tunnel must not have something above it, it may be sufficient that it is closed and long enough. I am not sure if we share these definitions in OSM.

"  This doesn't appear to be exhaustive / complete, tunnels could also run underwater, above ground and potentially in the future even in space, no?
>>> Many current underwater tunnels are also "underground", as they are often running in a man made structure (embankment like) on the ground or below the water body/river in the ground
