There was so many technical problems with just the name of the country changing from Yugoslavia, over Serbia and Montenegro, to being just Serbia. It took ages for big companies to follow up on this, and to this day some Google services still have a bug where some old accounts have Serbia and Montenegro listed as a country, they were never transitioned to Serbia - and as you can imagine that can seriously mess up payments and access to apps for account owners. Another TLD floating around to confuse people would be just PITA.
