Someone capable enough to design STL files from a dimensioned drawing is probably also capable enough to make a dimensioned drawing using calipers and the phone. I agree that it is a PR thing, but I also see that what they are doing as quite different from Apple. Apple is enabling hardware developers, Nokia is letting people who don't have mechanical skills make the cases. I think what would have been more interesting is if Nokia had released both STL as well as CAD files, which would allow for the modification that you point out.
