The intent of the lettercase stuff in the pathnames specification

whatever file system the file happens to be on

Besides, lowercasing in Unix is wrong as the file system is case-
sensitive.

Customary case is meant to be whatever lettercase is normally used in
file names on a file system, not whether the file system is
case-preserving or case-insensitive.  The examples in the dictionary
entry for MAKE-PATHNAME shows and the Issue PATHNAME-COMPONENT-CASE
mentions that customary case for Unix is supposed to be lowercase.

Yes. And *that* is wrong (the supposition that customary case for
Unix is lowercase). Modulo what Rainer said about having different
file systems mounted on a UN*X box (or whatever box), traditional UNIX
file systems are not exclusively lowercase.

The bottom line is that - as usual - the pathname spec is lacking in
many many ways.
