There is a thin line to walk between becoming a reimplementation of Windows API and getting developers to write native games. Linux went for the former, and it became irrelevant for a developer points of view, why develop for Linux and Vulkan when your Windows game works good enough? Maybe it will change in the future and developers will start to write native Linux games, but at the moment they don't. Apple chose the latter, and for now they hope to bring more developers to write native games. Maybe they will try a different strategy in the future, who knows.
