Hmm, what [1] actually says about that is

   Version ReFS 3.5 formatted by Windows 10 Enterprise Insider Preview
   build 19536. Added hardlink support if fresh formatted volume. Can't
   use hardlink if upgraded from previous version

so it's not exactly mainstream yet.

But given that, I'm content to say "you can use ReFS if you have
a version that supports hard links".  We don't need to support
work-in-progress filesystems.

            regards, tom lane
