What commenters say

• Some users appreciate uv's ability to manage script dependencies without creating virtual environments, making it a valuable tool for their workflow.
• The use of uv's shebang mode is seen as incredibly useful for executing scripts with dependencies.
• There is a concern about the maintainability and security of the Requests library, with some users recommending alternative libraries like httpx or aiohttp.
• The implementation of PEP 723 in uv and other tools like pipx and hatch is seen as a positive development for Python packaging and dependency management.
• Some users have mixed opinions about the creator of the Requests library, with some appreciating their contributions to the Python ecosystem and others criticizing their behavior.
• There is a need for better support for inline dependencies in LSPs, with some users currently using workarounds like manually creating virtual environments.
• The use of uv's sync feature can be useful for managing dependencies, but it requires careful handling to avoid destructive behavior.
