Practically the whole forum is a giant spoiler. It even says to "beware of spoilers" when the link to the forums comes up after you've finished the beta. There's even a whole thread for commands on here, so you don't have to put it as a spoiler. Still, it's up to you, but I won't be hiding the name of the command in my post
I do think it's vastly overpowered, but that's only because I also think refunding a skill is far too expensive, at least for the early game. You see, as you level up, refunding skill points gets more and more expensive. At the slow rate you gain gold and the high rate you get experience, you have to get to at least level 6 (for me) for it to be possible to even refund a single skill point. That's why, at least in the early game, it's much less boring to respec, otherwise you put all your grinding to waste, and you have to reset. Yes the grinding is fun, but at the rate it would go without the respec command, I think it would get tedious very quickly.
Anyway, I think all the commands are getting removed upon full launch, or at least this one is.
On a more personal note, it hasn't detracted from my game time much, with approaching 600 hours of play
