Re: MS, how about recognising EXT,HFS+ formats... FFS 2021.
ZFS is not just a file system, it's also a raid-like storage subsystem that does have a few licencing tentacles on top, so I don't see that happening any time soon (just like the others you mention, only even less soon than those).
Native NFS would probably be the first as it's available already, only not as an option in a default install.
