My 2¢:

I think the policy is that the ox-latex ain't going to track packages.
Aaron made some patches for this some time ago, but they weren't
included.

So the question is should it be a default package?

I think not.  E.g. tabu isn't loaded.  Amsmath isn't loaded if you
generate a matrix.  Also, a kitten dies every time the length of
org-latex-default-packages-alist increases!
