My honest experience is that S0 is a godsend, when you use a device on a weekly basis S0 is good enough and it just works, no messing and fiddling and tweaking, just running.
Chasing "real sleep" gives me nothing but pain. Also Android devices "sleep" fully awake so it's really "what people are doing".
the way I parsed this was; so it's not really a problem unless you want to use your computer the way you want to use it.
I get things are complicated, and hardware support is a mixed bag. But it doesn't have to be this way.
