I don't see myself disabling nested quotes, but there are probably some better defaults.

Maybe by default "Reply" doesn't grab any of the nested quotes and there's a "Full Reply" button that does. Or maybe there's a "Toggle Advanced Mode" user-option that adds buttons beyond "Reply" and "Edit".

I believe that would be a much more viable option. Or maybe a "reply" button that only quotes the new text, minus the quotes, and a "quote" button, which grabs it all. Whatever you choose, I believe it's a great idea to make it a separate option.
