One of the goals is to make the components loosely coupled at the top (so a product can choose among them as needed), and also pluggable at the bottom (so you can swap out implementations as needed, for example logging and monitoring). I expect that some of this will end up upstreamed into Kubernetes proper if it's broadly useful (autoscaler work, to pick an example), but this is still super early so let's see what people want. And yes, we're documenting the control plane APIs, the data plane requirements, and the contract for serverless container environments, with the hope that they can be reimplemented consistently wherever needed. One of the explicit goals is workload portability, so separating spec from implementation is critical.
