It’s not a deal breaker, but then again, you have flying WW in the current comic, and most modern animated portrayals of her have her flying. I understand that those are different mediums. If DC doesn’t want her to have that power at all, then for the sake of consistency, it needs to be removed across all media. WW being Zeus’ biological child isn’t an iconic aspect of her character, it serves no grand purpose, and hasn’t been around as long as she’s flown, but that’s what we got in the movie.
