For us, the DX of uv for dependency management is much better than just using pip and requirements.txt.

To be clear though, we only use uv in the builder stage of our docker builds, there is no uv in the final image.

Main reason I now use uv is being able to specify a cool down period. pip allows it but it's with a timestamp so pretty much useless..

And that doesn't prevent me from running it into a sandbox or vm for an additional layer of security.

Mainly the "project" system. I'm only developing python in my free time, not professionally so I'm not as well versed in its ecosystem as I would be in PHP. The fact that there's tons of way to have project-like stuff I don't want to deal with thoses. I used to do raw python containers + requirements.txt but the DX was absolutely not enjoyable. I'm just used to it now
