The Subsystem for Unix-based Applications (SUA, formerly WSU and née
Interix) does expose NTFS’s case sensitivity, but FWIW it was
originally developed outside of Microsoft and independently from NTFS
(and a few years later).

It looks like NTFS’s designers simply didn’t feel completely
beholden to the limitations of the Windows API.
