For people who had working hibernation, it may seem so.
For support staff, and for hardware & OS vendors, dealing with customers complaining about hibernation or S3 sleep not working those states were so infuriating and definitely NOT a solved problem.
Example failure modes:
— Doesn't wake when told.
— Immediately wakes instead of staying in low power state.
— Performs a cold boot when trying to wake.
— OS disables desired state with no explanation.
— OS disables desired state which has worked perfectly on that machine for month/years, and OS claims it has been disabled because it is not compatible.
Then they should've worked on fixing those problems, instead of adding even more new ones.
(I admit I haven't used systems with broken hibernates, or at least not any where a little it of troubleshooting could get it working, so that may skew my perception of it.)
