Windows implements ACLs in a far more granular way than macOS and most other Unicies, however (with the exception of Slowaris).

Comparing to DOS or what? No one runs Win10/11 on FAT now, while NTFS has access permissions and ACLs.

What does that even mean? NTFS file access permissions (35 years old at this point) are far more powerful than 1970s-era Unix permissions model.
