The machinery added in #17483 is currently used only by services. Not sure if I miss any other resource but most don't (and should since the client functionality is already in place: #18101).

issues/gaps with current implementation:

• export is not implemented for list (Possible Bug: kubectl get --export for singular item omits namespace #41880 )
• export does not remove self links (Self-links are not cleaned up when exporting resources #33767 Kubectl get --export includes namespace information for pods #57898)
• export service doesn't know intent, sometimes drops a port that was desired (Possible Bug: kubectl get svc --export omits NodePort #28551)
