People should be able to convey Debian packages (including source
packages) across such computers.  There are all sorts of situations
where a user may for whatever reason have to do so.

Note that even Debian systems sometimes mishandle this: ISO9660
(without Rock Ridge) and VFAT filesystems, both of which we commonly
use for distributing our own software, are case-insensitive.

Yes, this could be avoided by never using those filesystems and only
ever providing our softare as ext2 (say) instead of VFAT, or whatever.
Hopefully you can see why we don't do that...
