I don't think it's difficult to get a name approved in Denmark, thus extending the list of approved names, if it's a "real" name for example from another language/country. Made up names are probably not getting approved.
My sister's name, while a perfect valid name in Denmark, has a foreign spelling so it had to be approved.
In 1987 a boy was named Christophpher which is not a legal name. The mother was fined and fought in court until 1995 where she lost and was threatened with even heavier fines. The minister intervened and the boy was allowed to keep his name. However, the name was not added to the list of legal names.
