 - builds are non-reproducible for one reason:
   - there isn't a public API to reset the ID clojure uses for naming anonymous functions, which means anonymous AOT function names are non-deterministic
 - When using gen-deps, I haven't found a way to identify :provided dependencies. Those have to be added by hand for now
-- Do not use `user.clj`. If there is a user.clj at the root of your classpath, it will be loaded every time a new Clojure runtime is created, which can be many times during an AOT job. Additionally, dependencies in the user.clj are invisible to `gen-build`
