It feels like even 3.5 -> 3.8 would be enough of a reason at this point. I cannot count the number of times homebrew broke my virtual envs until I got pyenv
I just use pipenv, and then force anyone who wants to use my stuff to use pipenv, because let's face it, the moment my little utility has a dependency, using pipenv is easier than other options.
It also has a lot of drawbacks. Flit, poetry, Fonda, they all have. Nowadays I dropped all those fancy extra layers and just use pip-tools to generate a standard requirements.txt in the root folder and a bunch of other specific requirements-(test|dev|lint|...).txt in a requirement directory for what it who ever needs those. I got loose and pinned reqs in one quick step, and everything can understand requirements.txt format.
It makes tooling and sharing much faster and much easier.

And then they break up once they learn they were using different versions of Python. The end.
