> What sort of advantage do you imagine a build system like Bazel would provide for you? Build my C (or Rust, or Odin) Python extension, package the Python app with the extension and whatever other dependencies are required (e.g., generated protocol buffer libraries) into a Docker image, push the image to a docker repo, and apply changes to a Kubernetes deployment with a single command, and without doing any unnecessary work like rebuilding those native extensions if nothing has changed.
