Ok, do you have any certainty about the earliest BIOS date where _PR3 is used? E.g. if the minimum date is lowered to 2014 without checking for _PR3, would it be likely to miss out some models?

Can you add me to any relevant threads? I'd like to help get this fixed for 4.9.

I will, but did you get any feedback from the Windows architects yet? I'd like to get some solid reasons that support lowering the version requirement.
