This change is an option, but even in your example there's non-callout text that's part of a bullet list that no longer has a bullet associated with it.

What I'd like to see instead is just what oldframe does. Let's just indent callouts inside of lists.

Now, in a perfect world, I think this callout should be either outside of the list or off to the side. It's awkward even in OF.
