It's worth remembering that a Mac virtually never supports an OS released before it. They usually ship with a special build of the current version, and later point releases of macOS support the hardware directly. I wouldn't call that a scarce resource problem, but a convenient way of not having to create backwards compatible hardware. Just build hardware sensibly within your corporate world view, perhaps tweak it a bit for the latest version of Windows, and that's all you need.
