Wouldn't that make more sense as a hypothetical output format for "log --graph" rather than something you'd want to emit from the commit-graph? Presumably you'd want to export in such a format to see the shape of the repo, and since the commit graph doesn't include any commits outside of packs you'd miss any loose commits.
