Hi Ihor,

yes, the patch is just a step towards consistency, but I think is is an
important one, because it
makes org-mode not generate illegal/faulty LaTeX code.

As for the photo-finish, I have been thinking the following that we can use
the 'toc' document property.

Values nil and t work as intended in all backends. This means rewriting
this part in ox-latex.el.
Additionally, we add a new value 'toc:latex'  to keep the current behaviour
in ox-latex (at least, other backends could also implement it).

Coming from the LaTeX world, I lean towards the current ToC handling in
ox-latex.el (once fixed). It is closer to what I have been doing for the
last couple of decades ;-)

Once we agree on a way forward, I'll start coding.

Best, /PA
