Venv doesn't do dependency management, it just provides an isolated python environment. By default, poetry uses venv for environment isolation, but also does dependency management.
what about pip freeze to requirements.txt for manually but solid dependency management under venv? pip takes care of dependencies be it venv or poetry, requirements.txt will record what's need so you make your project reproducible and portable. what else does poetry bring to the table? If there is a strong selling point I would like to try poetry again.
yarn came out great but these days I switched back to npm for the sake of simplicity of my workflow, especially npm absorbed yarn's good features.
same thing happens to parcel/webpack, the neat new tool beats the old players, but then the old dominant one catches up by taking in good stuff from its smaller competitors, quickly.
