I’ve seen that suggested a few times before; a related suggestion that I found more compelling was related to a particular old-style alarm clock. At the time it was set for the clock would make a small click, then a few seconds later, a loud buzz. The owner of the clock could tell how well-rested he was by whether the click or the buzz woke him up.
I don’t think your division quite divides reality at the joints- I can get up to an alarm even if my day will be ruined by lack of sleep, but I generally will sleep long periods if I don’t have an alarm set. (If by ‘oversleep’ you mean ‘not take alarms seriously,’ then why argue that group 2 must use them, when they don’t use them well?)
I agree in the general case but not the particular. Staying in bed for ten to eleven hours persists even when I’ve done so for months, and other tests of sleep deprivation suggest I’m fully rested. Blackout curtains seem to be a significant contributor; it’s less pronounced when I use the sun as a gentle alarm.
Yes, probably. In Italy roller shutters on windows are ubiquitous, and keeping them shut all the way down will make it much easier to me to sleep until noon or even later; whereas if I go somewhere with no shutters at all it’s pretty hard for me to stay asleep long after dawn (though I’ll feel sleepy again in the afternoon). (But personally, no matter how dark my room is, it would be nearly impossible to sleep nine hours more than three nights in a row or so.)
