This doesn't seem to be possible for now, since we can't use Nix to replace the builder image.

The Nix package for the AWS CLI overwrites the base Python package and environment, so that any Python in the Nix shell has a number of libraries pinned to versions that are specific to the AWS CLI. That means we can't use our own Python code in the Nix shell because the versions conflict with the AWS CLI.

Closing.
