So we should have 1 single shell command to do literally everything?

before poetry and pipenv was a thing, pretty much everyone was recommending the virtualenvwrapper script instead of using venv directly... so yes, thats what it ultimetaly always ends up as.

One might invest 20 seconds to learn how to use it, but to each their own :)

Not what I would or wouldn’t do personally, but what happens generally in practice.
