Windows has ReFS. From the looks of it, it has some modern features. But I doubt that’ll ever be readable on a Mac.

> The ability to create ReFS volumes was removed in Windows 10's 2017 Fall Creators Update for all editions except Enterprise and Pro for Workstations,[4] which would seem to indicate Microsoft is no longer intending ReFS as a general replacement for NTFS, at least in the near future.

ReFS isn't meant as a mainstream FS. It's a pure storage FS that is meant to specifically work with backup applications for space saving purposes and with Hyper V. You can't even boot an OS off it, and the overhead from the block cloning technology simply cannot be compatible with normal OS usage.
