Whether or not something *can* be executed is irrelevant for text/* vs.
application/*. Relevant is whether something *must* be executed for the
document to be usable.

#+title: I disagree

* Firstoff
because this is a valid org-structure.
* Second
because you can use this.

#+begin_src bash
echo "even the embedded source here"
#+end_src
* Test
If you could not read the two arguments
_without_ first processing this section with org-mode
then I am wrong. If so, please tell me /"could not read"/.
That said: If you tell me /"could not read"/ I know
that you *could* read this section, so you would be wrong.

* Conclusion
Org mode documents belong into text/*

application/* and text/* are not distinguished by their domain, but by
whether they are readable as plain text.

Same for your other points.

Best wishes,
