I don't know how it currently looks but I agree there should
be such a function in vanilla Emacs.

Maybe something like this?

(defun push-last (elem lst)
  (when (listp lst)
    (setcdr (last lst) (list elem))
    lst) )

(setq lst '(1 2 3 4))

lst ; (1 2 3 4)

(push-last 5 lst) ; (1 2 3 4 5)

lst ; (1 2 3 4 5)
