When one invoke org-edit-special at the line containing an #+INCLUDE, it opens a new buffer with the referenced file. Although, if an #+INCLUDE contains the :lines clause it will not respect what is written in it.

Is there a method to enforce opening file at the place referenced by the :lines parameter?

If you look at the source code for org-edit-special, you'll see that all it's doing when called on a line containing #+INCLUDE, is calling org-open-link-from-string with the filename as a string.

In that sense the answer is no, there is currently no Org built-in setting you can change to have org-edit-special respect the :lines clause.

You could hack org-open-link-from-string such that it takes an additional optional argument linenum, and hack org-edit-special to read the line number from your :lines clause and pass it to org-open-link-from-string.

Something like (UNTESTED):

(defun org-open-link-from-string (s &optional arg reference-buffer linenum)
  "Open a link in the string S, as if it was in Org mode."
  (interactive "sLink: \nP")
  (let ((reference-buffer (or reference-buffer (current-buffer))))
    (with-temp-buffer
      (let ((org-inhibit-startup (not reference-buffer)))
    (org-mode)
    (insert s)
    (goto-char (point-min))
    (goto-line linenum)  ;;;;;;;; ADD THIS LINE ;;;;;;;;;;;
    (when reference-buffer
      (setq org-link-abbrev-alist-local
        (with-current-buffer reference-buffer
          org-link-abbrev-alist-local)))
    (org-open-at-point arg reference-buffer)))))

and in org-edit-special change this line:

(t (user-error "No valid file specified")))))))

to something like this:

(t (user-error "No valid file specified"))))))
  nil nil ((string-match ":lines +\"\\(\\(?:[0-9]+\\)?-\\(?:[0-9]+\\)?\\)\"" value)
            (match-string 1 value))

I guess this could be done with simple advices, but I wouldn't know how.
