refer-clojure exclude + defn, failure in symbol resolution

[jasonjckn]

I have a namespace declaration with

(:refer-clojure :exclude [assert conj])

and inside that namespace I defn conj

(defn conj
  "Like [[clojure.core/conj]], but for LensSchemas."
  ([?spec x]
   (...............util/conj ?spec x))

  ([?spec x & xs]
   (apply ....util/conj ?spec x xs)))

I have another namespace which requires and aliases this namespace and use the conj function, but Cursive says

I'm relying on this option, since i'm on polylith... if that matters at all
