I assume there must be. If I specify `foldmarks:nil' the if-statement in
line 294 evaluates it as false:
#+BEGIN_SRC emacs-lisp
(format "\\KOMAoption{foldmarks}{%s}\n" (if with-foldmarks with-foldmarks
"false"))
#+END_SRC

Same as above. `subject:nil' causes the code to skip the when-statement in line
301.
#+BEGIN_SRC emacs-lisp
(let ((with-subject (plist-get info :with-subject)))
(when with-subject
(concat
(format "\\KOMAoption{subject}{%s}\n" with-subject)
(format "\\setkomavar{subject}{%s}\n\n"
(org-export-data (plist-get info :title) info)))))
#+END_SRC
Note, that untitled prints the subject but without a prefix. Setting it to nil
hides the subject altogether.

Me too.
