> As soon as you use a Dockerfile you have reproducible builds

That is extremely optimistic. As soon as you do anything involving an update - `apt-get update` or similar - it's not reproducible any more, and of course you do need to do those things in most images. And if you don't need to do that, you can probably avoid doing the whole Dockerfile thing in the first place (although that may not be so easy if you're not set up for it).
