I do have:
- language-specific indentation and
- highlighting
in the Org buffer itself...

Just put this in your .emacs file:

#+begin_src emacs-lisp
        ;; fontify code in code blocks
        (setq org-src-fontify-natively t)

        ;; preserve spaces and `tab' characters in source code blocks
        (setq org-src-preserve-indentation t)

        ;; same effect for `tab' as in the language major mode buffer
        (setq org-src-tab-acts-natively t)
#+end_src

That's not a problem: if you turn on the "comments", you'll see every chunked
delimited in the tangled buffer.

If you play within both files, yes, that's a real potential danger.
