I for one enjoy the convenience of automatically installing python versions. Yes I know how to do it manually. Yes it is possible to install multiple versions. But that does not mean I want to do it every time, just to test how things behave in different python versions. For that, it's also okay if it does not install the most performant version of the interpreter.

You only have to do it once per version with this approach. Then you can create venvs from that base, and it's basically instantaneous if you do it `--without-pip`.
Sure. We've had system package managers for decades. I install a major version once a year and it gets automatically upgraded to the latest patch version by my system package manager, just like everything else.
