Basically, it means recent Nvidia GPUs will become viable using open drivers sooner, since developers won't need to update/port the older open OGL driver, and can instead just use Zink (OGL -> Vulkan wrapper). OGL support itself is important because accelerated compositors (like those that use Wayland such as recent Gnome/KDE etc) and older games native games rely on it, as well as many other pieces of a typical Linux desktop.

In the long run, competitive open drivers will mean greater longevity for these cards. There are AMD cards that are pushing 15+ years that are still usable today because they have open drivers.
