It doesn’t matter if the clay origin was confirmed or if she’s actually Zeus’s daughter. Rucka made it macrocosmically-clear that the gods granted Diana her powers. Even if she has to be Zeus daughter in defiance of all sense or continuity, her incredible powers are still the separate gifts of her patrons, like how neither Hercules or Perseus can fly or talk to animals without other gods allowing them to.
Even Shea Fontana went with this explanation. Her arc maintained that Diana’s body might be enhanced, but it was enhanced through the gods’ blessing.
The fact that Robinson is contradicting both those stories is his fault and his fault alone. Not even DC’s. As people have made clear, he could have gone with this pointless Zeus birth retcon and still had her powers come from all the gods. Instead he’s shown pretty abysmal understanding of both Wonder Woman’s stories from within the last two years and of Greek mythology in general.
