> Why is the "requirements.txt" file a stupid flat listing of all transitive dependencies with pinned versions? It makes it harder to change library versions even if there are no true conflicts.
My friend, here is what you seek: https://github.com/jazzband/pip-tools
requirements.txt is flat because it's really the output of `pip freeze`. It's supposed to completely and exactly rebuild the environment. Unfortunately it's far too flexible and people abuse it by putting in only direct dependencies etc.
If you're writing packages, you don't need a requirements.txt at all, by the way. Package dependencies (only direct dependencies) live in pyproject.toml with the rest of the package config. requirements.txt (and pip tools) are only for when you want to freeze the whole environment, like for a server deployment.

hatch plugin to use pip-compile (or uv) to manage project dependencies and lockfiles

Project mention: lockfiles for hatch projects | /r/Python | 2023-12-06

I came up with hatch-pip-compile - it's a hatch plugin that connects your hatch-managed virtual environment to a lockfile managed with pip-compile. The plugin detects whether your environment or lockfile is out to date and automatically syncs them when needed - and it's fast!

A plugin for Tox that lets you install test environment dependencies from the Poetry lockfile
flitenv
