Ha! I remember this being announced. I vaguely remember running a few nodes with ReFS about 6 years ago, which felt like a spiritual successor, but I’ve not used Windows since then so have no idea if ReFS ever caught on in the server space.
ReFS is not a spiritual successor. It was built by the maintainers of NTFS because they were bored of just doing maintenance and wanted to do something cool, like the boys over there at ZFS.
