> Regardless of how it must be implemented, if this is a desirable feature then this explanation isn’t an absolution of Linux but rather an indictment: its development model cannot consistently provide this product feature.

The problem is: the specifications of ACPI are complex, Windows' behavior tends to be pretty much trash and most hardware tends to be trash too (AMD GPUs for example were infamous for not being resettable for years [1]), which means that BIOSes have to work around quirks on both the hardware and software. Usually, as soon as it is reasonably working with Windows (for a varying definition of "reasonably", that is), the ACPI code is shipped and that's it.

Unfortunately, Linux follows standards (or at least, it tries to) and cannot fully emulate the numerous Windows quirks... and on top of that, GPUs tend to be hot piles of dung requiring proprietary blobs that make life even worse.
