Comment:
Is there really a hard run-time dependency on `git`? Should `docker-cli` depend on these backends, or is it more appropriate to depend on `moby`? (I use Docker very passively and am not sure how `docker-cli` would function without the `moby` engine.)

Even if depending on `containerd` instead of `moby` is appropriate, you can drop the `runc` dependency because `containerd` depends on `runc`.
