The practical change that's happening is that in future versions of Kubernetes, they're removing support for using a shim for telling the Docker daemon to run containers, and focusing on just using containerd (which Docker uses under the covers anyway). It's kind of like if you had a shell script to launch programs, and it used to move the mouse to press icons, but now you've deprecated that and will only run programs directly.
