Complete agreement here, I actually cooked up something similar to this a while
ago and posted it to the list, but never committed it. There should probably
be an option to answer yes where applicable, but also an option to outright fail
on any prompt.

Something like --noprompt={fail,yes}, defaults to fail. Unfortunately this doesn't
look very intuitive but my brain isn't thinking of anything cleaner at the moment.
