ATR-42 is turboprop but I have always landed it with power levers at flight idle, otherwise it floated. So once again: it's really type/version specific.
Now I see where it's coming from; less than adept mediaperson presenting continous descent approach as if it were flameout pattern. Don't worry about idle approaches down to idle landings, they're not going to happen. Very little saving would be achieved for steep increase in risk.
