"I'm more concerned with ways to help more outsiders import a codebase in the first place."

This. The pain point that mu addresses is huge. I haven't really looked at the project in much depth yet, or played around with it, but I love that you are tackling this issue. I have spent way too much time wandering around a big code base trying to build mental models of what's going on, and thinking to myself the entire time "there's got to be a better way."
