I would not want that as the default. Yes, it is one standard use case.
It would break other standard use cases, like creating ordinary
documents, though.

Perhaps variant adding such a patch could be added to org-latex-classes,
or at least mentioned in the docs to org-latex-classes? That way you can
use this "class" version for such cases without adding unnecessary
uglyness to other org-created documents.

Another possible approach would be a change in the export functions.
What really is needed here, from my point of view, is that the export
adds a superficial paragraph to a heading in the case that there's no
content at all. Nothing should be added if the heading has sub-headings,
I count that as content. In case there is no content at all, then some
form of breakable vertical space should be added. I don't know enough
LaTeX to find the least intrusive way, though I'd try \vspace{0pt}.

I did never dig into the export functions, so I don't know how difficult
that would be.

Just my thoughts,
Julius Dittmar
