Please file a bug[1] against the documentation you're referencing,
probably the Power Management Guide?  That will help the guide
coordinator ensure that the issue is appropriately addressed. Point 1)
seems especially relevant, that much should be explicitly clear.

fwiw, it seems like hibernation is generally falling out of favor these
days.  I know not everyone has newer systems, but those that do have
machines that use shockingly little power on suspend, and cold boot
faster than a resume from hibernate could ever achieve.

On point 3, one would hope that resuming from hibernate didn't require
you to manually edit the grub configs every time :)  I'm not well versed
in the area, but it smells like at least one bug/deficiency  from here.
