Well, some of RF transformers are used with the primary being at the plate potential ()anywhere from 40V to 200V) while the secondary is at pretty much 0V. In these cases you do want some separation. Not likely but due to the enamel defects it is theoretically possible for the two windings to short.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
