Not just because of the power level involved, but because IMO the focus of a monk's development should be on gaining fighting skill rather than additional "gimmicks". They have enough gimmicks already.
"The fear of death, its risk each time, is one of the most stimulating parts of the game. It therefore behooves the referee to include as many mystifying and dangerous areas as is consistent with a reasonable chance for survival." - J. Eric Holmes
