I'd say the opposite instead: we need Kubernetes distributions, just like Linux needs distributions. Nobody wants to build their kernel from scratch and to hand pick various user space programs.
Same for Kubernetes: Distributions which pack everything you need in an opinionated way, so that it's easy to use. Now it's kinda build-your-own-kubernetes at every platform: kubeadm, EKS etc all require you to install various add-on components before you have a fully suitable cluster.
I think the Operator pattern will grow to become exactly what you describe. We're still at the early stage of that, but I can see that a group of operators could become a "distribution", in your example.
