[Tagging] place nodes for continents?

I think there's too much redundancy in using is_in:continent.
it is useless, for example, to say that a street + the municipality
+ the region + the country is all in the same continent.
it is enough to tag the largest polygon with is_in:continent and erase
those that provide the same information redundantly on objects included
in that polygon.
this would limit the number of is_in:continent to one per country or a
few per country for countries with very scattered territories (e.g.
overseas territories for France)
The other solution is to a merge of all polygons having the same
is_in:continent value to make a (multi)poylgon, possibly simplified,
for each continent. this is neither more nor less verifiable than the
information currently in the database. but it would strongly allow to
simply use it (e.g.: how many power plants informed in osm in africa?)
