Code review comment for ~bryce/+git/oci-dev-tools:implement-build-and-status

One consideration I'm debating for the json is that I know the object itself is transmitted from launchpad in json format already, so I need to think about if it might make sense to just dump that directly, rather than generate it myself. OTOH the launchpad object may be a bit noisy, and there may be additional information that this script can add beyond what launchpad provides. So I want to play around with it a bit before deciding.
