About the Python ecosystem
Python is the language of data science, ML, and glue scripts. PyPI ships 500K+ packages. The abandonment pattern is similar to JavaScript: most projects are bus factor 1, and the single maintainer often loses interest after 2-3 years.
PEP 541 is the formal mechanism for transferring ownership of an orphaned PyPI package. It's the most-developed handoff process of any ecosystem — if a maintainer is unreachable for 3+ months, anyone can file a PEP 541 transfer request. The PyPI admin team will reach out to the maintainer (or their estate), and if no response, transfer the package.
The Python ecosystem has a healthy culture of 'adopt the abandoned library' — many of the most-popular PyPI packages today are forks of abandoned ones. The median drop-to-first-PR for Python projects on BreakPoint is 21 days. For data scientists and ML engineers, this is the most actionable language to adopt in.
