Yes - but then their final stage is built on top of an Alpine container, and they complain about Alpine's package manager + OS files being included in the image.

If their final stage was based on scratch or distroless, the Docker file size would have come out to the minimal ~90MB result too.

Yeah, I don't understand that part either. If you want to be able to shell into the container and poke around, use Alpine by all means, but then don't complain about a C runtime being included. If you want a minimal container for your static executable, use scratch.
