I agree there isn't too many powerful FWD cars and it's traction that's the problem. But I disagree that they are any more difficult to make oversteer gracefully than anything else. The reality is that most people are average at best and understeer is the easiest telltale sign that ultimate grip is being approached. The reason that most FWD and AWD car understeer is that most people brake when shit happens, that's fine when it's the nose that has let go but it's a disaster when it's the tail which have let go.
The snap you are describing is the equivalent to a tank slapper with a rwd car, the outcome is just as problematic for the average driver and just as dangerous.
