A simple macro like

--8<---------------cut here---------------start------------->8---
(defmacro setc (&rest args)
  "Handle ARGS like `setq' using `customize-set-variable'."
  (let (body)
    (while args
      (let* ((var (pop args)) (val (pop args)))
        (push `(customize-set-variable ',var ,val) body)))
    (macroexp-progn (nreverse body))))
--8<---------------cut here---------------end--------------->8---

could fix that (perhaps expanded to not add itself to the "user" theme
as it would usually be used within a persistent init.el), if added to
the core.

Then all you need to do is replace a setq with a setc.
