The metal fork limiter was only a real problem on the short lived rim brake version of the current shape SS Evo. The Disc brake version was quickly updated with small metal inserts inside the headtube at the point where the bump stop hits the inner head tube if turned too far. The bumpstop itself is also not made of metal, it is moulded carbon.
The cases where the bump stop caused the headtube damage were pretty much caused by carelessness anyway IMHO - if the bump stop wasnt there, letting the bars swing round so violently would have cracked the top tube from the bars whacking there instead (not to mention damaging the fork crown, and also ripping any hydro cables out).
I have a supersix evo disc and have no idea how anbody could cause the headtube to crack from the bump stop - you would have to basically turn the bars at a full 90 degrees with some considerable force to make it happen - this doesnt happen under general use. Sure, it can happen by accident, but if it happened to any other bike it would just result in a cracked top tube instead.
