Thank you for understanding!

Thank you for understanding. You have given me pointers what to do, my
personal case is closed, though I am not the one who knows how to
properly patch it, and I do not see yet that there is consensus, as
few people did not understand about user preferences and rather speak
how EWW should even take care of security issues for user instead of
giving user freedom.

I have done following to make it work personally:

(defvar eww-content-type nil)
(put 'eww-content-type 'permanent-local t)
;;; in eww-render I put:
;;; (setq eww-content-type content-type)

(defun rcd-eww-content-type ()
  (cond ((string-match-p "text/x-org" (car eww-content-type)) (org-mode))
	 (t (eww-mode))))

It is not working best, help me if you know how. I wish normal
eww-mode when it is not org-mode.

(add-hook 'eww-after-render-hook 'rcd-eww-content-type)

And now I can browse Org files from within Emacs.
