What is the reason for hiding the slots on a timed node?

Bad as Gathering is, Fishing is so much worse. A myriad of external resources is practically required for Fishing, and while they EVENTUALLY started adding some of that information in-game (time and weather requirements for certain fish), what they have is vague yes/no answers, and even those are unavailable for Big Fish.

That actually seems to be gone in ShB. All ShB fish just show ??? for time/weather/conditions (except the Crystarium delivery ones, which display like normal.)
