I've been in the Clojure world for over 10 years but I don't really recognise the problem you're calling out here. There will always be libraries in an ecosystem that lack maintainers, particularly if they did not see the hoped adoption or an alternative de facto solution has emerged. Many Clojure libraries are conceptually simple and solve one problem well, so it's common for them to reach 'feature completeness' and not see much activity after that. clj-commons has also ensures the active future of many libraries. A friend and I adopted a library we felt was stagnating and still had lots of useful features to add. I don't see this more in Clojure than anywhere else though. Any more examples that need engineers? Onyx always seemed to be entering a crowded space.
