As I mentioned before, most (If not all) turbine brand ECU´s have this function also incorporated.

You're the second guy to mention that, but the problem is, if the ECU is still getting pulses, even though they may be erratic from a PPM glitching episode, the turbine will continue to run. I know of no ECU that will monitor the incoming pulses and filter them like an IPD receiver will, so the only way to get reliable shutdown on loss-of-signal is to use PCM.
BTW, the point still stands that if you truly had a PCM failsafe due to interference, then the aircraft would have been unflyable with PPM as well. I would suspect that most of the crashes that guys attribute to PCM "lockout" are really, either battery failure, switch failure, servo failure, or RX crystal failure...
