Why isn't this built on top of the kubeapi?

Why wasn't this implemented as CRDs on the kubeapi? It seems to have a nearly identical yaml format and commandline interface.

It's built on agent-subtrate which IS built on the kubeapi but seems to do so indirectly via a hosted backend server.

I assume it has something to do with etcd churn or something.

Take a look at https://github.com/agent-substrate/substrate/blob/main/docs/architecture.md#problem-statement. It explains many reasons why another layer like Agent Substrate was needed.
