I'm trying to understand if something like that is necessary. The
documentation and mailing list have suggested =:wrap org= before and I
suppose what I'm looking for is someone with either an understanding
of the code or history using this argument to say either "Yes" or "No"
to the question of, "Should that be producing \begin/end{org} in the
resultant LaTeX export?"
