People just cheat the perma-death anyway, so what's the point?

As long as it's possible to backup the saved game folder to restore it in a perma-death game, people are going to do it that lack self restraint. Would be better to learn more self restraint than ask the developers to spend money/man hours to build in what people will just end up bypassing anyway and self restraint may just help those people that lack it in real life anyway.
