The Python package manager uv is looking extremely promising:

• https://astral.sh/blog/uv-unified-python-packaging

We should consider adding support for it to Heroku's Python buildpacks:

• Python classic buildpack: Support the uv package manager heroku-buildpack-python#1616
• Python CNB (Cloud Native Buildpack): Support the uv package manager buildpacks-python#248
