It's polarizing to call it dead, I'd say it's very much not, but it's fairly clear that the Docker people would rather have you using their follow-up project Swarm (which I think is supposed to be something like Kubernetes lite?). A major example of this is the ability to define resource limits being removed from docker compose V3 files unless you run it in swarm mode (which is mostly compatible).
