That's using a Linux VM. The idea people are asking about is native process isolation. Yes you'd have to rebuild Docker containers based on some sort of (small) macOS base layer and Homebrew/Macports, but hey. Being able to even run nodejs or php with its thousands of files natively would be a gamechanger in performance.
Also, it were possible to containerize macos, or even do an unintended vm installation, then it’d be possible for apple to automatically regression test their stuff.
