>What most projects do is to separate "common" namespaces and use the `.cljc` extension to indicate they're multi platform, and keep platform specific things in namespaces with `.clj`, `.cljs`, etc.

This is exactly what I witnessed when finding the example above.

Out of frustration, I tried patching shadow-cljs one afternoon and was able to implement :refer :all as well as automatically generating :require-macros when needed to some extent, but I haven't put the time to make it work fully. I don't think this is a limitation caused by the lack of a Clojurescript compiler that can run in a Javascript runtime. In short, I don't think this is an essential limitation of the way the language is hosted within its target language, unlike things like Vars, which are not introspectable at runtime in js.
