[Tagging] Subtag for place=locality?

In Belgium (where i map), we generally use this tag for place without
population that have a name ("lieu-dit" in french (look at this wikipedia
article) <https://en.wikipedia.org/wiki/Lieu-dit>), like a crossroads (like
"Carrefour de la Justice" (literally "crossroads of justice")), a field, a
part of a forest or some hills. It is often very old names that are shown
on various topographic map (generally the name is the same than in the
past, as we can see them on maps from 1700 ...) and it is really useful to
locate ourself.

Thus i would not limit to the sub-type that you propose (which are only
considering "abandoned places") because there are a lot of cases where they
were never anybody there (we can sometimes find that the crossroads are
inside a hamlet but the crossoroads itself is not inhabited). Also,
locality=junction isn't related to railway (if you look at example, it is
<https://www.openstreetmap.org/node/52259975#map=17/52.77889/-6.48665> or
crossroads <https://www.openstreetmap.org/node/262804588>). So i would use
add sub-type for all those "never inhabited places".
