Even if contained it can be dangerous. Light twin piston airplanes, likwise double the odds of engine failure, but due to the dramatic loss of excess thrust, the good engine actually becomes the problem, e.g. Vmc limitation. The assymetric thrust force can exceed control surface force needed for controlled flight. The solution is never go below Vmc airspeed, but if you do it requires immediate power reduction. And that has consequences that often inhibits committing to the proper action prior to loss of control. In most cases power reduction commits the pilot to landing sooner than preferred, and in a likely suboptimal location.
