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.
