I'm very skeptical that one can transition a team to another language and have everything go perfectly.

To summarize:

* learning curve successfully flattened to a week by... reading two books.

* painlessly interacting with a large C++ code base

* no team member dislikes the change, instead they're feeling energized and this has even brought back some from near-burnout.

* Rust is extremely productive

I can accept that the tooling's good, community's nice and type system's a pleasure to use, sure. But people don't change so easily and such drastic changes in large code bases don't go right by default.

If all of what you said above were true, every C++ codebase would have been switched yesterday.
