Our Commentary ​

uv is quickly becoming a staple in the Python ecosystem, much like Bun or Turbopack in JavaScript. These kinds of changes to default project structure are always a bit disruptive, but often for the better. I've been meaning to switch to src/ layout myself, so this might be the push I needed. It's good to see tools evolving.
