I'm okay with Bruce being perpetually held responsible for those, even though I've always thought he was right to have them and even though he wasn't the one implementing their use. (Completely irresponsible of him to have them accessible to other people, though.) It's not that I think Zatanna should have to apologize for that every time she saw Bruce, but I think she should be ready for it.
But what's done is done. I'll take that retcon, no matter how stupid.
