Note that this tag has major problem due to fact that there are multiple competing ways how Earth may be divided into continents. Given low number of continents, fact that collecting this data on ones own is easy and that depending on OSM data is not useful (moving, deleting or changing name of place=continent node would have massive impact on a map) and that it is deisirable to tweak label placement tweaked for specific map it is dubious whatever this data is useful.Also, "One of the seven continents: Africa, Antarctica, Asia, Australia, Europe, North America, South America" is a subjective selection, there are competing methods to divide landmasses into continents.
