Never had an engine failure, have you?

Also just shutting off the engine doesn't stop the prop from
windmilling. To do that you have to have a prop that fully feathers
and even then they don't always stop fully.

As a matter of fact I have. In a 172 and the prop continued to spin until I
was on the ground and didn't stop until the AS was about 45.
