Pretty good list that I mostly agree with. I think the only point of contention I may have is with using timbre--having tried it in the past, I found it didn't do much that clojure.tools.logging couldn't do for most use-cases, and added configuration complexity while not sparing me the trouble of dealing with logback XML configs and whatnot--Java logging seems to rears its ugly head no matter what you do, especially when using a fair amount of interop as our project does (and as any big project probably does to some extent). Seems like it's best to simply suck it up and learn how Java logging works. But, it's probably worth giving it the benefit of the doubt, and perhaps I should give it another shot--it's been a little while since I last tried it so maybe it's improved, or maybe I simply didn't understand well enough how to set it up effectively.
Otherwise, lots of great points. One other thing I will say about Schema (https://github.com/plumatic/schema): while it's a lifesaver in a lot of ways, its mere existence really does expose some of Clojure's deficiencies when it comes to the type system (or lack thereof). I'm probably in the minority in the Clojure world but I really wish that it had better static typing and a more sophisticated type system sometimes. I've mostly made my peace with it but once in a while I look longingly at ML-family languages from afar...
