Not exactly sure what you’re asking?

Many of the issues you’ve described have come about due to the natural evolution of hardware. The GeForce 3 still had significant parts of the D3D7 fixed function TnL hardware in the silicon, but as hardware got faster at some point it made sense to use those transistors for something else and emulate the pipeline using shaders, which might not be 100% accurate in all usage scenarios.

Drivers have also become increasingly complex, not just because of the API’s offering ever more functionality but also the compatibility effort they’ve gone to to ensure the end user doesn’t blame the hardware or drivers for some stupid/non-compliant things the developer of the software has done.

There’s a resource cost (financial or time) for everything - silicon, development, code complexity, maintenance, testing et al. so removing legacy functionality for obsolete API’s or compatibility support for long gone titles is an easy win.

Basically a modern equivalent thread of "fog isn't working in Nvidia TNT but works on ATI Radeon 9000" while also a mix of "my Nvidia doesn't render the colour correctly on Windows 10 while it did on 8"

Playing DirectX 8-9 on modern hardware usually adds some amount of visual glitches. But that's mostly driver thing and is fixed by using Vulkan wrapper or Wine (Linux).
