Maybe I haven't investigated enough how they are used, but shouldn't the XXXContainerBuilders be in deployment rather than the runtime packages?
The builders are specific to each project so we did not want to load all of that into the deployment module.
The idea was to split each module into two: a runtime package and a deployment package. That happened for the app client, the latest, but we naver got around to refactoring the others. I think there is a Jira on it but can't be bothered to look :)
