I like the spirit of this but for dealing with multiple clusters, kubectx is pretty standard, always returns highlighting where you are and we don't have to type in the cluster name in every command. Also avoiding "kubectl delete" seems such a narrow case, I can still delete with "k scale --replicas=0" and possibly many other ways; at this point you are better of with a real RBAC implementation.

isn't kubectx the problem, not the solution? You think you are in one context but you are actually in another. You wanted to tear down the dev deployments but you nuked the production ones instead.
