We are aware of the issue but in order to co-exist and be consistent with the way other devices, paths had to be different than what was defined in the stock rom. We could either break extract-files from CM or from the stock rom and we chose to keep it compatible with CM. If you flash CM you can then extract the files from there. It should be easy to write an unzip-files.sh too, which could grab the proprietaries from a precompiled cm build.
