Then you just need to create a case-sensitive partition, no? What's the
*technical* issue of doing that? And that cannot be more challenging
than testing your kernel changes, right? So it won't raise the bar of a
potential serious kernel contributer.

How do you know it's "typical"? I just googled it and confirmed I'm a
Gen Y ;-) and I'm not using vscode or any IDE, a lot of Gen Y, Z and
Alpha developers I know either use Linux on their desktop/laptop or they
don't use IDEs. May my experience suffice to say it's not typical? Or is
it the case where I thought me and my friends are the whole world? ;-)

They are not "case-insensitive" OSes, they support case-sensitive
filesystems, and they support them for a reason, so just use them. With
your changes, it may be OK at clone time, but as soon as you do some
serious development involving `git bisect`, you might be very frustated
that your setup doesn't work.

So your solution is incompleted (not handling the git history), and your
goal is a bit personalized: it's only useful to people who want to
read/edit Linux code without running it and don't want to use a
case-sensitive filesystem, and that's not very persuasive. I don't think
we can accept the solution or commit to that goal.
