You can enable case sensitivity per directory. That moves the problem to making sure any tooling they use doesn't have an issue with that though. E.g. Sublime is capable of opening something like C:\Example\file.txt instead of C:\example\file.txt but trying to open both at the same time doesn't work. Normally Sublime would put the folder path in front of the name but on Windows it assumes the folder path is not case sensitive and performs the "is this file already open" check with case insensitive logic.

The story with enabling long file paths is even sadder. Explorer doesn't support them, for example.
