syntax-quote (`) actually resolves the symbol, while regular quote doesn't

compare
(require '[joker.os :as os])
(println `os/t)
Candid 2019-05-28T02:44:02.010300Z
prints joker.os/t
Candid 2019-05-28T02:44:15.010500Z
(require '[joker.os :as os])
(println 'os/t)
Candid 2019-05-28T02:44:24.010800Z
prints os/t

that's why qualified symbols inside syntax-quote "use" required namespaces
Candid 2019-05-28T02:47:08.012800Z
so the former doesn't trigger "unused namespace" warning while the latter does

it will still work when it can’t be resolved though, but you’re right, when it’s there, it is used:
user=> (defmacro foo [] `foo/includes?)
#'user/foo
user=> (macroexpand '(foo))
foo/includes?
user=> (require '[clojure.string :as foo])
nil
user=> (macroexpand '(foo))
foo/includes?
user=> (defmacro foo [] `foo/includes?)
#'user/foo
user=> (macroexpand '(foo))
clojure.string/includes?
