Snyder had the right idea in removing the red diaper. It was modern, fresh and simply time to move in that direction on film IMO. The argument there's too much blue without them doesn't hold water anymore for me. Having them back just feels like a giant regression. Batman films since 1989 have gone without diapers and it's been fine. It's okay in animation and comics, but right now in a 2024/5 movie it's just out of place and a source of amusement. Don't worry, I get all the historical meaning behind them.
