I wouldn't say that deconfirms them any more then Mewtwo's trophy "deconfirming" him. People want DLC, people will buy DLC, people want Lucas/Wolf, Lucas/Wolf are easier to make because some of their moves are in the game, Lucas/Wolf are added as DLC. The custom specials may have just been added early on because (presumably) Sakurai didn't initially plan DLC until Nintendo made him do it for $$.
