I think you're arguing a different case here - one that is also
interesting but about something else, and that's "negative mapping".

There is indeed a difference between "a road that doesn't have a name in
OSM" (the name might simply not have been surveyed yet) and "a road that
does not have a name in the real world".

How to signal the fact that the road doesn't have a name, is indeed
something that people think about, and it is useful information not
least because it keeps mappers from unnecessarily trying to find out the
correct name ;)

The fact "there is no railroad here", however, is not something that I
would consider useful; because where would it end? I'm standing at a
lakeshore - there's no railway here, also there's no forest here, and no
building, and no rugby pitch, no telephone booth, and no power lines.
Certainly you're not suggesting we map all these negatives.
