I'd be very interested in a tool for diffing that gave some broad overview of how things have moved around. Otherwise, the kind of refactoring where you break things apart just creates a pull request that's harder to get oriented in. Which is a shame because a harder to gloss code review can disincentivize the changes that are needed most.

Conversely, it's just so easy to add an if statement there or any early return here, and over time you've got a 400-line method with like 100 branches and an Avagadro's number of possible paths. But you look at a two-line diff and say, "Hey, this looks reasonable."
