It's still somewhat common, but over the past couple of decades we've created package managers like QuickLisp that allow calling external dependencies in Common Lisp as easy as it is in Python (and even systems to allow us to interact with Python to get access to its ecosystem), plus a version of Common Lisp (Armed Bear Common Lisp) that runs on the JVM to get access to that ecosystem (not to mention the Lisp-adjacent language Clojure).
