In my personal experience the other huge benefit is you now have a source of truth for documentation. Since your API definition is code you can leave comments in it and code review it all while having a language that is very approachable for anyone who is familiar with the C family of languages.

For a newcomer having `message Thing {}` and `service ThingChanger {}` is very approachable because it maps directly into the beginner's native programming language. If they started out with Python/C++/Java you can say "It's like a class that lives on another computer" and they instantly get it.
