The OS is the one providing the filesystem, it should define and support how it's used (including providing standard utilities for manipulating it, both from programs or by the operator) rather than leaving the programs to figure it out between themselves. (After all, if the text storage format didn't matter to the OS, why would we bother using the CRLF format on windows at all? I submit that third-party programs did not spontaneously come up with an arbitrary convention that everyone would use a different text format on Windows; rather programs use CRLF when running on Windows precisely because the standard utilities that ship as part of DOS/Windows expect that format)
