I'm much more likely to need to go and attend to something at a moment's notice rather than save-scum and find games that are all "lol you'll have to replay from the last checkpoint, sucks to be you" to be tedious and irritating.
That's where suspend saves (what I was describing) would come into play. You still get to save your game to go do something at a moment's notice, and come back to it as if you hadn't been gone at all. You just can't reload that save game, so if you need to go do something again, you'd need a new suspend save, which you would be fine with since you just wanted to save your progress and not start over from a few seconds ago.
