The Case of Switch Hit!!!

The MCC has ruled Kevin Pietersen's switch hit as allowable. This is seen as a success for batsman as this allows them to whack the ball changing their stance without prior notice. But reverse hits have been a part of the game ever since, then why was this raised before MCC??
The original Reverse hit was the reverse sweep. When this shot was played only the bat's position was reverse , both the body and stance remained same. This new concept of switch hit has the player suddenly changing his stance and his grip and then executing the shot. It can be seen as a bowler changing from over the wicket to around the wicket without telling before hand. So if a right hand batsman plays this shot , its like a whack over mid wicket played by a left hand batsman. The first instance of this was KP's shot against Muralitharan back in 2006. He recently scored 2 sixes against Newzealand employing this shot. This was the reason for this to be referred to MCC.
Now since they have ruled for it citing it provides a chance for the bowler also to strike. Will we see more of this innovative shot or will this be confined to batsman like KP??
