Got it. Thanks for the explanation!

Ok.

Then let's not consider it for v5.11. For now I think the userspace tool/daemon can check 'dmesg' for the existence of ACPI S4 state as a workaround. This is not ideal, but it should work reasonably well, assuming the tool/daemon runs early enough, so the kernel msg buffer is not yet filled up and overwritten. :-)
