It's actually not so simple.  The LFN support that you use on Windows 9X
is the same code Windows itself uses to access files, albeit through a
backdoor.  In other words, the LFN API is simply an alternative entry
point into the Windows' native file I/O routines!

So, if Microsoft would want to add this support to DOS, they'd need to
rewrite the Windows file I/O code so that it would work inside DOS,
and then add that code to MSDOS.DOS and IO.SYS.
