-1. It does happen that files need to be reuploaded because of a bug in the release process and how people manage their code is really *their* business, not that of PyPI. FWIW, I am getting increasingly annoyed how PyPI and pip try to dictate the way package authors are supposed to build, manage and host their Python packages and release process.
