Oil itself would not reliably isolate two metal layers lying on top of each other. The field forces would differ widely depending on the random thickness of the oil. Paper is a much more precise spacer. This is sonically and security-wise important .The oil impedes burning of the paper IMO.

PIO caps is a very well proven 'old' technology, which seems to be superior to waxed paper. The people who've made these had a lot of hands-on knowledge how to make them optimally. Most are retired now. Jensen has activated this know-how in house. One such retired specialist from swiss company Leclanche is making the very expensive Kristall Kaps.

Contact is IMO made 'normally' by a metal spray on the radial ends, and by welding on metal foil caps.

Paper (like cotton) has a very important property in being less prone to static charge-up. Static electricity is involved in negative sonic effects (these are sometimes called Martin Logans or Quads - just joking!) .
The oil IMO has two sonic effects: It eliminates (to a certain degree) ionizing and maybe also some effects like MDI, ie. supected micro-discharges which are sayed to create kind of a faint back-ground hiss. Together with the paper it also damps any quick movement of the foils, which otherwise might happen under peak discharges or normal AC use.
