In my case? Recreating a build environment in the process of debugging an issue with a build script and trying to get the runtime environment lined up just so; with a side objective of an exploration of the madness of how Python as a language handles packaging (part of which was what kind of footguns are presented by the lang specific package manager, which funnily enough also seems to be completely oblivious to the runtime version it's executing in). >The package maintainers ship 3.6 by default for a reason and they know better than you! /s Maybe then! Not anymore! It really does infuriate me because it breaks every aspect of the principle of least surprise and conventional software packaging practice.
