Request for New certificate Kubernetes Certified Architect or Kubernetes Certified Expert(CKE)

I've achieved CKA and CKAD , put CKS as target.

Beside of this I would like to see certification which covers design and architecture topics.
When building on premise clusters you face a lot of quesions, challenges to bind best practise solutions.
These consepts are also needed on cloud deployments.

I would suggest the following topics for this certificate:
On-premise and Cloud clusters
Designing onpremise clusters based on best practises
Kubernetes cluster advanced networking
How design secure cluster (some parts from CKS or security from SA point of view)
Microservices Application Development (12 factor for microservices) on Kubernetes
Migrate monoloth application to Kubernetes microservices.

Maybe some points is out of scope of Kubernetes certifications. I just wrote suggestions which I considered as challange for me and friends.
