Another example would be how pip, and venv have some edge case failures on Debian or Ubuntu. Repackaging is a constant struggle, especially when the software adds new features that are not thoroughly tested by the packager.

Another caveat to consider is that people tend to blame the first party (Python developers) when this happens, while the problem is really caused by packagers. Bad things may happen less often with a packager in the middle, but when they do, it’s generally a lot more difficult to deal with exactly because of the added layer and complexity.
