Well, hibernation is also different from power off in that RAM contents are saved prior to the power off.
I think, but am not certain, that "suspending" has been what kindles have been doing since day 1, but with occasional wakeups to communicate with the mothership if wireless is on.
I think the Oasis 2 wakeup from deep sleep is too slow to be a resume from suspend and don't see how a deeper suspend would represent a significant power saving. I live in an area where it is forbidden to leave home unless necessary and in the early months of the shutdown I unconsciously went from splitting reading 50%/50% between my Voyage and Oasis 2 to reading 100% on the Voyage. After a few weeks, it dawned on me to check the charge level on the Oasis every month or so. The decrease was tiny. I've since started reading on the Oasis during daytime and have forgotten the rate of loss. But it was small enough that it seems more likely to be a power off than a suspend.
For the past few years, every time I raise a flash wearout concern, it gets pooh-poohed.
