Do you have a useful & understandable mental model for "delta"-based operations like "rebase", "revert", etc. for arbitrary commit DAGs? Admittedly I haven't sat down to think about it for very long, but I feel like I'm not the only one who feels like lots of operations (including those) become difficult if not impossible to reason about with nonlinear history.
