For Linux there's the richacl's (https://en.wikipedia.org/wiki/Richacls ) which was an attempt to add NFSv4/Windows style ACL's to the Linux VFS. It never went upstream though, AFAICT largely because the VFS maintainer thought such ACL's are stupid.

The VFS maintainers are still not very warm about the idea, the current stipulation, IIRC, is that an in-tree FS should support it before it gets support from the VFS layer.
