I don’t think so. I think Patty recognises that they’re unnecessary for Diana’s character. If they’re truly needed, then they’ll magically appear during her climatic battle with a villain who warrants a magical sword and shield. Even then, hopefully the Sam Browne belt doesn’t return. Whoever thought blocking / breaking Diana’s chest symbol with an ugly, brown harness was a good idea? They wouldn’t ever do that to Superman’s S or Batman’s Bat-symbol!
