Neat! Okay, yes, I can definitely see the value here, particularly if all or most of an image is otherwise able to be expressed in terms of things that are deterministic, such as language ecosystem package managers with lockfiles. It seems like you're cutting an interesting track on providing a better way than Dockerfiles with their imperative layers, but pragmatic enough to not insist on taking over the whole world like Bazel or Nix.
