People have been citing persons (e.g. what she said) as well as works (e.g. what was said in her book) for ages

But this is almost always a case of someone referring to the words of someone else to help make a point relating to their own message; a citation, or attribution, is always contributing to a point or argument being made.

I don’t think a conversation, or a dialogue, is the same type of communication, and for that reason the ol li cite q example doesn’t sit well with me. I think dialogue needs its own element, but if we’re going to luck out in that area, then I guess we have to take the next best option, and if it turns out that the majority of authors go for it, then I guess I’ll follow suit as there probably won’t be any other option to consider.
