Then you've got ecosystems like Clojure where many projects are just considered done and used by many. You can pin these (and be warned if a new version still comes out, say for an actual security fix). There are Clojure projects so stable, without any know exploit (we're certainly not talking about daily npm exploits here), that haven't been updated in years because they are... Done. Simply done. Perfection.

Something to reflect upon too.
