I don’t think they actually dropped new available times. I think they only changed the logic that allowed for an available reservation that could now be booked as a F! Dining Package if the times were within the acceptable time range to be allowed as a F! Dining Package. I think most lunches qualify. For dinners, times would have to be early.
My date is 1/2, which already had limited to no availability prior to today’s change. I only saw times pop up when a non F! Dining package became available. At that point, both regular restaurant and the F! package were both available at the same time slot for booking.
