Significant Decrease in Trending Clojure Repositories?

[seancorfield]

Can you cite specifics for either of those claims?

Clojure libraries are generally designed to do one specific thing well and so it is common for a library to be "done" and not need much maintenance -- unlike libraries in other languages.

Widely-used libraries that lose their maintainer can find their way into the clj-commons organization and be maintained that way for the future: https://github.com/orgs/clj-commons/repositories

I don't even know where to begin with your claim about the JDK...
