The metal spikes often tore up the green surface, so most golf courses have forbidden them. As @saevel25 says, the PGA Tour must negotiate with the individual golf courses to allow their use, and quite possibly the other professional tours do the same.
I practice this shot on occassions. As posted above, it's a usefull shot to get the ball out of thicker rough to a more playable ball position. It matters little how far the ball goes, just as long as the ball is in a better position for the next shot.
I tend to use my sw most of the time. With a steeper, more verticle chopping motion, the club head will be less effected by the taller grass on it's way down to the ball.
It's a shot saver when done correctly.
