I was about to double-down on my earlier assertion that it wasn't worth it at this point in time (while agreeing that we would do it in the ideal case).
But it looks like Pipenv automatically installs a version of python via pyenv already if you specify it with --python. E.g: pipenv --python 3.7 install <package> First downloads and compiles python 3.7 if it doesn't exist on the system. Now this isn't a penalty we would want to incur on every task, but the path forward is maybe a bit easier than I thought. I still don't think anyone is going to have the time to work on it right now, but feel free to get a bug on file in Testing :: Python Test (and make it block `buildpython3`).
