The IL78 is a multipurpose aircraft with its value being the cargo capacity. It doesn't matter what type of aerial refueling system it comes with. The important point here is the immense capacity for liquid cargo. It is a stable and airworthy plane even with the tremendous amount of liquid on board. The fueling apparatus can be refitted. To do this, one needs only the storage tank, a means and method to extend the booms, and controls that can regulate the flow of fuel. As long as the universal fueling components are there (tank, fill, boom controls, and vent, the fueling components of connection and interconnect fittings can be retrofitted as required. The IL78 has the flexibility to also suppress fires with a deluge of water and fire retardant. It's the airframe that's important, not the specific pieces that the fitout comprises.
As an example, take a look at Israel. They purchase US fighter aircraft and heavy tanks. They rip everything out and refit them as they see fit. Like the airframes, tanks and heavy support vehicles are purchased for their frames and chassis. Not the other stuff.
I'm not sure, but I think the history and reason for the purchase was that this plane has a huge storage capacity. It was purchased originally for quenching forest fires. When that business didn't develop, the other primary role of the IL78 was promoted, namely it's great refueling ability. That's when TADF was born. At least to the best of my knowledge and research.
And of course, my humble opinion...
