I really hoped PyPI's required switch to 2-factor auth would require reauthorization to publish packages. But no, they went with "trusted publishing" (i.e., publishing is triggered by CI, and will happily publish a compromized repo). Trusted publishing would only have been a minor hindrance to the litellm exploit. Since they acquired an account's personal access token, the exploit could have been committed to the repo and the package published.
