This can happen but already for medium deployments the costs are so much lower that you can hire a bunch of devops managing a proper centralized RBAC-based k8s cluster which isn't over-provisioned nor under-utilized. And even if, it should be still significantly cheaper than anything from Google and AWS. But again, if a company runs a strong-margin business model cloud cost optimizations are the wrong thing to think about. Whatever, your solution is definitely a big step in the right direction.
