My editor does this independently of VCS, so that's not an issue. I get it, "last saved to disk" is a save point that is meaningful to you. The world you can move to is a world where you can have any number of these save points. "last saved to disk" would be "go back ten minutes" but you'll also "go back five" or whatever else. It's a much more general way of working.
