>> Why could't PIP just be an apt-extension? Because not eveyone uses an apt-based package manager. Python runs on quite a few platforms: https://github.com/python/cpython/blob/main/Lib/platform.py https://github.com/python/cpython/blob/main/Lib/platform.py Apt is not the package manager for most of those platforms. Thus an operating system package manager-based approach would not work for everyone. That said, several operating systems do "vendor" pip packages so that apt or the equivalent operating system package manager can install a known good version of the package. This approach can introduce problems, but it also can prevent problems depending on the operating system and programming language.
