I agree that treating production vs non-production as a dichotomy can be problematic, but that doesn't mean some systems aren't more sensitive than others.
Also security is not one dimensional. A system's required level of confidentiality might be very different from its required level of availability. Being explicit about this might be better than trying to lump different requirements into a "production" label.
