It is entirely optional, you seem to be completely ignoring that massive flaw in your argument after a few posts now.
If people want to use it they can, if they don't want to then it is their choice to be 'robbed' of that experience.
Personally, as I'm not 11 years old any more with hours of free time in the summer to ride my mountain bike then come home in the afternoon and play on the meagadrive or my mate's snes then I perhaps would be inclined to make use of the feature. As I mostly played Sega games and only snes games at a friend's house I'm quite keen to have a go with this mini snes, but having this feature, if there are really long winded games where hours of progress could be undone, is quite useful.
