Clojurescript creates lots of overhead on the runtime, I wouldn't recommend it for UIs that need to do more than very lightweight processing on the client and be really snappy. A 50k LoC codebase(as in Dark) in Clojurescript will be a nightmare. To scale a Clojure(script) codebase to that size requires lots of documentation and discipline(and lots of tests!), it can me made but it's not easy.
