Never having tried this, I am curious about how fast a light twin can roll right over in this situation. I know "it will depend on..." but are we talking seconds, tens of seconds?
I had an early King Air 90 that wasn't rigged properly nearly swap ends on me during landing, just by pulling the power to idle. I've had other airplanes in training that don't hardly want to show Vmc characteristics, but that would rather stall first (also a potentially dicey situation).
A multi-engine airplane is not dangerous if flown properly. This is why we teach students about respecting, experiencing, demonstrating, and avoiding the region in which directional control can no longer be maintained. It's not rocket science. It's common sense.
As noted previously, the rationale of retarding power on the good engine needs to be kept firmly in mind for anyone piloting a light twin.
