Guide to the PCB Plating Process: From Materials to Plating …

Immersion silver plating (or IAg plating) is a surface plating process that creates a thin layer of silver over copper objects. It consists in dipping the object briefly into a solution containing silver ions. Immersion silver plating is used by the electronics industry in manufacture of printed circuit boards (PCBs), to protect copper conductors from oxidation and improve solderability. WitrynaThis specification sets requirements based on performance criteria for the use of Immersion Silver (IAg) as a surface finish for printed circuit boards.

I think it all comes down to corrosion, the flatness of the finish and cost. HASL isn't flat so you can rule this out for fine pitch ICs or BGA, the gold over nickel ENIG is as flat as it gets and the gold surface is the least reactive so won't really corrode and last for years on the shelf.
