containerd has requested to move to the graduation maturity level:
https://github.com/cncf/toc/pull/165

The containerd community believes it has fulfilled all the graduation criteria:

- Have a healthy number of committers and at least two from different organizations: Containerd has had a variety of maintainers and reviewers since its inception, and currently have 12 committers representing Docker, NTT, Google, IBM, Microsoft, Facebook, Tesla, and Cruise Automation. They also have reviewers representing Alibaba, ZTE, Huawei, Docker, Microsoft and an independent developer.

- Document that it is being used successfully in production by at least three independent end users:

Containerd began life prior to its CNCF as a lower-layer runtime manager for the Docker engine. Continuing today, containerd has widest usage and adoption as the layer between the Docker engine and the OCI runc executor. However, as containerd and its CRI plugin project have merged in January 2018, the combined use of containerd and the CRI plugin has grown to include several public cloud providers, as well as several projects who are attracted to the simplicity of the Go client API library for embedding container runtime capabilities.
