This is cool. For dev, the docker runtime consumes an enormous amount of host system resources. Even with a 16gb RAM host machine, docker is really resource heavy for a development environment. If this can cut down on host system resource usage, that's a major win.
I assume they are running it on Windows - I've been running Docker Desktop on Windows for years, and it's backed by a Hyper-V Linux VM, which does seem to use a lot more CPU than running Docker on Linux.
