As said earlier the command is just for beta testing purposes since leveling up a new character every time to try out a new skill or a new skill combo was both boring and troublesome because of the few save slots. As far as I know the devs have not decided if they want a way to respec in the full game. I think that they are going to decide on this after they've almost completed the story since it would be easier to imagine how the feature would fit/act in the game at that point.
This is not a MMORPG so beta testers don't really have an advantage over others. Besides the beta testers wouldn't have to create a new character on release because they have already played the game and made a character with their prefered build.
