No one gets killed by an error in pedagogy. And the space program was launched on far more tenuous grounds than the NCTM reforms. The miracle is that we lost as few astronauts as we did. The Challenger explosion occurred in spite of caution; the primary causes were corruption/shoddy quality control and over-confidence based on past success. And if we'd waited for optimal conditions, we might never have gotten anything off the ground. Life is a judgment call and involves constant risk taking. If you're arguing that the NCTM reforms are ill-founded and hastily implemented, let's hear some evidence. Otherwise, my point stands: we'll NEVER be in optimal position to implement change - at least not to the satisfaction of the most conservative among us.
