[tex-live] kpsewhich case insensitive?

I know that this is a very old thread, but, I keep thinking about it since
I read it. The latest versions of windows 10 (1803) with WSL installed,
allow to use "case sensitive" for folders using the "fsutils", that is,
"fsutils" is not recursive and must be made folder by folder.

Some days ago I am working on a collaborative (La) TeX project using
github, linux and windows and I have created a small script (csdirtree) to
leave dir trees  with "case sensitive" activated (ideal when using
"auxtree" loved...).

In the future maybe it could be an option to install TexLive using pseudo
"case sensitive" using "fsutils" in win10.

use strict;
use autodie;

use Getopt::Long qw(:config bundling_values require_order no_ignore_case);

my $enable  = 1;
my $disable = 0;
my $status  = 0;
my $help    = 0;
my $verbose = 0;
my $null    = devnull(); # "null" device for windows

# error
sub errorUsage { die "@_ (try csdirtree --help for more information)\n"; }
