Rust by Example was actually not originally a Rust team project. It was an independent work that was handed over to the Rust team for maintenance by the original author.

As I understand, it received basic polishing and updates to make sure it was correct, but hasn't been edited much beyond that.

This history is accurate. RBE is pretty low on my priority list; finishing up the book and the standard library docs are much more important right now. I to try to keep up on PRs.
