The problem with this argument is that 1) bifurcation often still isn't available on enthusiast-level motherboards which are filled with features catered to hobbyists, and 2) all motherboards are using variations on the same handful of BIOS firmware images.

Same-slot bifurcation controlled by the BIOS requires basically zero additional testing. If it works on one board, it's pretty much guaranteed to work on another. After all, it's nothing more than a feature flag toggle.

They have already invested the money into developing the software feature, because some boards do have bifurcation. So why isn't it available on on all enthusiast-level boards? Or even worse, why are they spending extra time and energy into disabling it on cheap motherboards?
