Windows support

I am looking for a way to use containerd on Windows Server 2019 with a Docker CLI replacement like this one. I see there are Linux builds, but has a Windows port been attempted?

Long story short, containerd for Windows should handle graceful shutdowns for containers, but the current version of Docker is still using HCS v1 + some really broken stuff under the hood, meaning Windows containers have never supported graceful shutdowns (https://github.com/microsoft/Windows-Containers/issues/16).

There is no clear migration path for Docker to adopt containerd on Windows in the short term, so I would be fine with installing containerd on Windows (https://kubernetes.io/docs/setup/production-environment/container-runtimes/#install-containerd) but then I just need a proper CLI on top of it, other than 'ctr' which is very primitive and marked as unsupported/unstable.

I am not familiar with Go, but how difficult would it be to attempt a Windows port of this tool?
