6950 XT, Sonoma: Anyone using unfairgva=1 ? Used for fixing hardware DRM support on supported AMD GPUs

Hi, I am not using this boot arg, and from what I can tell hardware DRM works fine, but just curious if this is something we should use nonetheless?

Here is where I came across it:

I don't see it as a Whatevergreen boot arg (https://github.com/acidanthera/WhateverGreen), so maybe it is some sort of legacy arg?

thanks
