Thanks for that!  That is really cool and having the entries in the TOC
un-numbered is exactly what I want!

As a follow-up, it would be nice if I could mix
that now again with num:1.  That way I could add a TOC with depth 1
(only sections) and have them un-numbered.

But num:1 add its own '\setcounter{secnumdepth}{1}' (why?) which by default
comes later than than the #+LATEX_HEADER definition:

--8<---------------cut here---------------start------------->8---
#+OPTIONS: num:1
#+LATEX_HEADER: \setcounter{secnumdepth}{0}

* foo
This is foo.

** subfoo1
This is foo.1
** subfoo2
This is foo.2

* bar
This is bar.
--8<---------------cut here---------------end--------------->8---
