Comment:
Not depending on moby seems appropriate then. It also sounds like `containerd` and `runc` (and maybe `iptables?) should not be dependencies of `docker-cli` because people may wish to install `docker-cli` for controlling remote moby instances without pulling in underlying container runtimes.
