"\\penalty0" may be safer (perhaps with additional "\\relax " or newline
for a case that next portion of text will be started from a number
without any space). I was not aware that penalties are not combined by
TeX, any is considered as a break point. There are various tricks like
\vfil\penalty100\vfilneg to allow variation of page height.
Maybe e.g. 100 should be used instead of zero to make less probable page
break between section and subsection titles. (Carefully prepared text
likely will have at least a paragraph before next level header. Anyway
nobody expects that early drafts are carefully formatted.)
There are should be a user option to disable this workaround and
probably an "#+options:" keyword. It should be carefully tested with
inline headings (\paragraph{...} and similar).
I still believe that it is a LaTeX issue. I see why it is not supported,
but any workaround may be fragile. I am really surprised that TeX does
not generate apparent warning due to a page of enormous height.

As to headings of arbitrary depth, HTML has <h1>...<h6> elements with
<h1> for page title, so just 5 levels of sections. Sometimes even <h4>
is hardly distinguishable from <h3>, especially there no other headings
are visible due to long text between. It is better to not abuse nested
levels of headings.
