As the kubernetes-client-api plugin is a wrapper for the kubernetes-client library can we include all the provided extensions too? Currently only the kubernetes-client, openshift-client and volumesnapshot-client seem to be included.

From the Kubernetes Client repo extensions it has:

knative
tekton
service-catalog
volumesnapshot
chaosmesh
camel-k
certmanager
verticalpodautoscaler
volcano
istio
open-cluster-management
