Removed or deprecated ISO alpha-2 codes normally get alpha-4 codes in Part 3 of the standard. This is a way to support flags for “countries” that are no more (but had existed after 1949 or so), because they split up, merged with other countries or just changed their name significantly.

Should they be added?
