Why is `lein run` not `lein trampoline`?

What's the difference between Leiningen and Clojure CLI tools and how should I use them?

I'm playing around with Clojure recently. The most loved dependency management tool in the Clojure ecosystem is Leiningen to my knowledge. But I also found Clojure has provided CLI tools which probably could replace Leiningen. Due to the limitation…
