Couldn't we just compare input and output?  Or is that not safe
enough?  E.g. in an over-simplistic form obtain dead pages via
something like this:

#+BEGIN_SRC emacs-lisp
(let* ((html '("dir1/my-page1.html" 
	      "dir2/my-page2.html"
	      "dir2/my-page3.html"
	      "dir2/my-page4.html"
	      "dir3/my-page4.html")) 
       (org '("dir1/my-page1.org" 
	     "dir2/my-page2.org"
	     "dir3/my-page4.org"))
       (html-sans-extensions (mapcar 'file-name-sans-extension html))
       (org-sans-extensions (mapcar 'file-name-sans-extension org)))
  (mapcar (lambda (x) (concat x ".html"))
	  (dolist (x org-sans-extensions html-sans-extensions)
           (setq html-sans-extensions (remove x html-sans-extensions)))))
#+END_SRC
