So, flatMap and flat are added to Array in ES2019. In which form they should be added to this proposal? What they should flatten - sets, arrays, iterables?

I'm not sure if there is any intuitive semantics for Map.prototype.flatMap and Map.prototype.flat. Set.prototype.flatMap is quite obvious, I will add it.
