I thinks it's fair to create an issue for removing this TODO ;)

+1, that said. I'm not quite convinced this is the way to go. Let's move this fix forward and discuss future steps in the opened issue

Hmm.. "fix" says nothing about the behavior. Could you rename this method to sth less vague? movePodLabels, extractPodLabel, etc.

labels, err := in.GetValue("pod.labels")
if err != nil {
return in
}
in.Put("labels", labels)
in.Delete("pod.labels")

return in
}
