Mistakes happen, maybe it's used in the manufacturing or fab phase to test something. Maybe it's used by the GPU firmware itself to perform some operations.

Maybe it was used by some older SoCs to do something and was just never removed.

Apple may not be a small family business but silly mistakes still happen all over the place in nearly every large system.

To quote another post by macran cause I feel like it's super relevant when trying to analyse how this kind of stuff comes about.

@nicolas17 @nil Correct. The question is, how many more of these fun bypasses are left undiscovered? The GPU is a huge amount of hardware and firmware.

Computers are so incredibly complicated now days that these kinds of hardware bugs are likely sitting around elsewhere as well, they don't come around that often because the amount of effort required to find them is likely a lot, which is likely only viable for a nation state actor.
