The fact is that it's so easy to write your own code in CL, that the majority of glue code in NPM, Maven and the likes don't make sense to be written.

An example can be taken from a comparison between VS Code and Emacs. In the former, you have a whole browser engine and quite a bit of code to implement an editor on top of that. In the latter, you just have some primitive and the rest of it is LISP implementing multiple applications. LISP encourages less layers because the data structures and the language are so flexible.
