Unofficial TLDs work fine without being special cased (well, so long as the browser is being pointed at the appropriate DNS server which knows about these entries), it's when the TLD itself is used as a URL you have to enter "http://tld http://tld." instead of just typing "tld." but any sub like "example.tld." still works automatically.
