I see automation closed this. However, I am curious if this is indeed something that needs to be addressed to catch up with K8s.

Looks like this was implemented with #4276 Is that correct?

[vepatel]

@brianehlert yes this one can be closed 👍🏼

[oseoin]

Closing as completed in #4276

I am fishing if configmap still works at all? Since I understand the command line option is still present, which implies the configmap code is still present. And thus to potential for someone to use both configmap and lease at the same time.
