@Brady Vercher - I can't speak for Chip, but a few ideas might include:

- fallback open graph image
- disable comments on Carousel
- auto-select/deselect Publicize checkboxes on Edit Post screen

A full list of Jetpack Hooks can be found here. And the Jetpack tips & tricks blog has a few ideas & code samples that you might find useful.

And thanks for contributing. While I can't speak to the backend stuff that George mentioned, I love the way it works on the frontend.
