I suspect that the similarities of meaning between countries are more by
coincidence than by design, unless they are defined by some
supranational body like the EU or UN. If X:de, X:it and X:fr appear to
mean the same thing, it doesn't mean there aren't subtleties which would
be lost for ever if the tagging was conflated.

In the UK a combination of admin_level and designation is adequate. The
UK local government system is not always hierarchical, however. At the
parish level much is unparished, and concepts like "lands common" don't
fit a perfect hierarchy. There are also Combined Authorities.
The UK system of local government means there is a wider-than-usual gap
between local authority areas and "places" (which I define to be the
answer given by a local to "where do you live"). The admin boundary
system and "place" demarcation (where that is possible) are completely
orthogonal.

Country-specific concepts require country-specific tagging, and there is
nothing more country-specific than local government. The only way to
avoid country-specific tagging is to agree on a common definition for
the whole world. This is OSM... Good luck with that....
