For one thing, it allows something (La)TeX tries to circumvent: page
breaks immediately after a section heading. In normal documents, that's
something you want to avoid as much as possible.

Perhaps another approach would be more fitting, but it needs changing
the LaTeX output routine: Have org add something invisible after a
heading in case that heading's body is empty. That makes page breaks
possible (after that invisible something) without changing the behaviour
for non-empty sections.

Just my thoughts,
Julius Dittmar
