Another great selling point of Clojure in big, evolving projects is architectural agility. The combination of dynamic typing and focus on data structures allows you to pivot your codebase even when it has grown out from infancy. Changing database model, splitting to different microservices etc. come relatively easy so you can perform a refactoring while still continuing to add new features.
To be fair other types of refactorings (e.g. changing some map keys from keyword to strings in a big codebase) are unnecessarily painful. But dev tools are getting better and better by the day.
