Actually what you are suggesting they do isn't exactly correct. Just identifying the changed files is not sufficient. See clause 2b in the GPLv2. Derived works _must_ also be GPL. Essentially, to do this right, the original model with textures and animations would have to go into a separate zip file that is licensed as is and then the derived configuration files would go into another zip file that is GPL'd.
