A common pattern in academic OSS is that you start out with code for a research project, it gets reused for a second research project, and then you realize that there’s a whole line of research here and the code should be split into “library for anyone doing this kind of research” and “specific logic for research project 3”, and the library belongs on PyPI but the specific logic for each research project only needs to be on a VCS forge and your research group’s website. How to do that probably deserves to be a tutorial in itself.
