Rey being a Skywalker would be PLOT-IMPORTANT, and Johnson flat-out says that the question of Rey's family is merely CHARACTER-IMPORTANT.
It seems fairly clear that part of the goal of the TLJ marketing campaign, such as it's been, is to mitigate people's expectations a bit. Otherwise, there's no reason for Johnson to answer the question he was asked about Rey's family and its significance to the narrative of TLJ on the whole, and no reason for his answer to take the form that it did.
