Just the other day, we had to create a requirements.txt with a single character . to get a tool to correctly install dependencies from our pyproject.toml. The tool only supports reading from requirements.txt and setup.py, but we had a pyproject.toml with configurations for many of the other tools we use.

I keep wanting to think it's improving over time, but the reality seems to be simpler than that. It's just changing over time. That being said, type hints were a welcome addition, and occasionally they add new features that make sense. They also add features like the walrus operator, but we don't talk about those.
