I don't know what you mean. The behavior referred to as softpoweroff in this thread has _never_ been planned to be delivered to the final user, since it was considered to be inferior and a lame workaround to real power management problems.

Seriously, we achieved suspend to ram as first step and it was kept as backup solution, just in case dynamic power management would prove to be too hard to reach. Which has never been the case.

So i don't understand where this expectation for a "fix" comes from.

Iirc an unofficial version was delivered, but what it does is basically cut the connections and disable wakeup sources other than the power button.

Which makes it a softpoweroff spoof.
