Of course, just kidding—it just takes a significant amount of time to even start reviewing when you look at complex subsystems. But no matter how complex the subsystem you're looking at is, as long as your curiosity doesn’t stop and you keep spending time on it, you’ll eventually get there.
And yeah, being good at using Git is such an important skill in a project with a long history (and being able to find and read old mailing list threads too...)
