It is an interesting discussion though. While I respect very much folks on the other side, for me once you add a save game feature that allows reloads like KC:D has then you are in the time machine business.
Your character can now use a time machine, there is no getting around it. That time machine can be in the shape of a bed or a schnapps bottle but it is a time machine the same as save anywhere is.
Given a time machine completely removes any sense of immersion anyway, I prefer mine to be convenient.
