The following code doesn't work:

#+begin_export latex
\[
n!=
\begin{cases}
  1 & n=0 \\
  n(n-1)! & n\ge 1 \\
\end{cases}
\]
#+end_export

Because of the following error message:

But I can use #+begin_latex and #+end_latex instead.

I read the former syntax is new and will be released with Org Mode 9.0.
Is that true?
