I'm not talking about auto-including packages, nor do I suggest to
include lot of stuff in `org-latex-default-packages-alist'.

My point is: if "wrapfig" is there, "rotating" should accompany it, or
both should be removed from the variable. Also, there's no reason for
"longtable" to be included.

IOW, I'm discussing a very practical point, not the general status of
packages in the LaTeX export back-end.
