This was probably instituted not just for countries that no longer exist, but also for cities which have disputed sovereignty. I'm thinking specifically of Jerusalem: inhabitants of East Jerusalem who consider it part of Israel, and Palestinians there who think of it as their capital, can list merely the city without having an argument about specifying Palestine or Israel as the country.
