To be honest, I do expect to find a project provided with a pipenv/poetry setup, just like I would expect a haskell codebase to have a cabal/stack setup, and a java codebase to have a maven/gradle setup. It is true that most recent languages ship with these from day 1, but ecosystems rarely lack this kind of stuff. I mean, even my vim has a package manager nowadays. As for whether you want to salvage old code that isn't provided with package management, it's up to you. But you would have this kind of problem with any old, unmaintained codebase.
