Other independent nations, this is why I suggested the promotion of all
other admin_level=2 if we went this route.

A more radical approach would be to drop admin_level entirely and rely on
the way the relations are nested.  However, I imagine the thought of
processing that would reduce all but the most stoic of data consumers to
tears, not to mention the fragility of mapping this way, the difficulty in
doing so with OSM's typical philosophy of incremental improvement and the
myriad of problems that results when borders are fuzzy and hard to pin
down.
