It does feel like one of the side effects of containers is that now, instead of having to worry about dependencies on one host, you have to worry about dependencies for the host (because you can't just ignore security issues on the host) as well as in every container on said host. So you go from having to worry about one image + N services to up-to-N images + N services.
