Use unregistry to remove the Docker registry dependency?

One of my biggest frustrations right now in setting up a kamal deployment is setting up the Docker container registry.

There's a new project called unregistry that lets you push images straight to remote Docker servers over SSH with docker pussh myapp:latest user@server.

This feels totally in line with Kamal's philosophy but I'd like to check with someone who knows a bit more about the architecture in this project before I attempt a PR.
