This goes against the principle of tagging the relation, not the
members. An admin area is syntactically analogous to a multipolygon and
it would be a shame to introduce yet another polygon tagging paradigm.
What are you thinking for other types of boundaries? boundary=political,
boundary=national_park come to mind. Will they be treated differently to
What do you intend exactly when you say "maritime boundaries"? That part
of a (national) boundary which crosses water? Or some other definition?
