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.

That´s not exactly true, the ACT diversity system provides reliable programmable failsafe with PPM. The system monitors signal integrity of both receivers and is able to establish safe transmission even if one RX completely fails. The integrated data-logging can be downloaded after each flight into a Palm for further investigation and storage on a PC. It logs signal strength and how often during a flight one (or even both) RX´s lost signal and in how many cases the diversity sys was able to recreate full connection. Very useful. Seems to be a well engineered system.
