uv can install a version of python of your choosing in addition to pulling the specific versions of libraries specified in your lockfile. it's extremely dummy-resistant.
Right, but that means the end user has to have (or install) uv, and then you ship them all your code, and then they can use uv to run that. That's a development workflow - and exactly what I meant when I said that uv didn't solve distribution in the way a language like Go or Rust does by producing a single binary.
