Ah, but do you love sleeping itself, or the context to safe and secure sleep, the luxury of a warm bed and the knowledge you can get the sleep you need, getting up when you like and feel refreshed? I get that that is what you are saying is a part of the quality of sleep experience, but those qualities are not really about duration, you either have those privileges or you don't. If you are lucky enough to have a biological clock requiring less hours per night to enjoy them fully, that's ok. I would agree though that to forgo those qualities intentionally over an extended timeframe is a curious choice.
