I've worked with oil insulated and cooled systems. They are a mess. They
all leak, unless the entire thing is permanently sealed (e.g oil filled
capacitors vacuumed out and filled and crimp sealed at the factory)

A bit of a fire hazard too.. Unless you run (very expensive) silicones or
(contaminated with dioxins) PCBs

And, capillary flow of the oil through the wires, although you could use
solid, uninsulated wires to get on and off the board, if you were clever.

I'll bet they have to change it more often than that.  This isnt something
like a pole transformer.
