It is because of the new enamel. If there were a considerable voltage difference, but there is none here. Layering in output and power transformers is more of a concern, but still, the voltage difference between subsequent layers is still not enough to break-down the coating.
P.S. I have used stretch-wrap between layers on output trans - more to hold layers in place than to insulate. We'll have to see how that lasts, but I am confident that it will outlast me.
I just found this picture that I titled "Worst Cap" from a 37-116: 
--looks like a bank of RF coils rather than the osc bank.
