They don't have to. NVIDIA at least has the userspace driver, kernel driver,
and DDX version-locked so it's impossible to have any mismatches. With AMD, I
think it's a bit looser, but whatever WSI mechanism they're using for GL,
they're also using for Vulkan. They probably left DRI2 behind a long time ago
and don't really have this problem.

Yes, which is why it's good that it only controls a warning and no actual
driver behavior.
