The POSIX namespace in NTFS is important for implementing things like SfU and WSL1. That's how they get proper POSIX semantics for filenames and links. Win32 programs can technically use it too, but it's an NTFS-specific feature rather than just a Win32 one as I understand it. (It can also be used on Linux when using NTFS drivers. AFAIK, it's usually the default option for new files in ntfs3g.)
