I tend think the opposite. Developing for Android I found the Java build process and maintaining a solid development environment a headache. If that follows on to Clojure I can see why it wouldn’t be as popular even if the language itself is overall better.
My experience would make me agree with you. Developer experience around tooling in Clojure makes a lot of assumption around prior knowledge of Java ecosystem.
Elixir, on the other hand, welcomes the newcomer better.
