I do not see input=”country” as a very good solution to problems that go far beyond just a method of masking data entry. Because (in the end) a location is asked for, a place of residence, place of birth, delivery address, etc., you can avoid problems by having people put a marker on a map. On the backend you can match these coordinates with what is needed for handling the request in both time and location. I would be from Lugdunum Batavorum in 275 BC!
