I suspect that any brine that did form would consist of really minuscule,
isolated droplets rather than extended films or pools of liquid.

Agreed that there won't be pools, but I'm actually leaning toward chemically active films, rather than solution droplets.

Many (many) years ago, I prepared divalent cation solutions and spectrophotometer baselines for enzyme binding spectroflouroscopy. (I.e. I mixed chemicals and did precise measurements of how color changes with concentration).
Part of that included reviewing how water works. How water as a polar fluid shields charges, how water structure changes when things are dissolved. Basically, treating water as a jenga piece, how do you remove it, or how do you add it?

This is relevant here, because the activated adsorbed single molecule films that salts accumulate, are going to be reactive.
Oddly, due to stoichiametric requirement, some reactions just won't work unless you get eh, 6 water molecules,
while other reactions will work with just 1, 2, 3 or more..

I suspect that there will need to be boots on the ground before the question of brines can be resolved.
