I rarely even use requirements.txt and never use it in my personal projects.

I just pin the project's direct dependencies in the setup.py file and install the folder directly. I know it might cause bugs with different developers (or the CI) using different versions of the upstream dependencies but I guess I trust the developers who create each library I'm using. The moment I directly import something from what used to be an upstream dependency, I pin it too.

So far this approach hasn't given me trouble, but I'll still take a look at poetry based on what I read in the comments here.
