>But if you knew power was failing, which is why you did the ^S in the first place, it would not just suck, it be worse than that because your expectations were shattered.

The only situation I can think of this being applicable is for a laptop running low on battery. Even then, my guess is that there is enough variance in terms of battery chemistry/operating conditions that you're already playing fast and loose with regards to your data if you're saving data when there's only a few seconds of battery left. I agree that that having it not lose data is objectively better than having it lose data, but that's why I characterized it as "not a big deal".

You've not been to my house.

Contractor: "Hi, we need to kill the power to the house now."

Me: "Oh, ok, let me shut down my computer."

And, everything I've been reading lately is simply that there's nothing safe about this. How is shutting down a computer ever safe now? How long do we have to wait to ensure our data is flushed correctly, by everything?

    and they're killing the power 0.1 seconds after you told them the computer is shut down? If the drive only lost the last 2 or 3 seconds of writes, you'll be fine.

    that's a good point. maybe the drives still get some residual power from the motherboard even when the computer is "off", and that's enough to finish the writes?
