Ah I didn't realize that they're actually instanciable from the WMI 
repository in an application, but that makes perfect sense with how easy

It was created at a time that the ACPI WMI BIOS attributes interface 
didn't exist.  I've understood that the general direction is to use the 
WMI BIOS attributes interface in the future.

That's why I was suggesting using both, if such a transition happens 
then this driver would be ready for it.

I don't have a strong horse in this game, but I see what you mean in 
terms of general compatibility.
