There are two issues with this solution.

The first is that editing non-trivial latex code embedded in an elisp
string quickly becomes tedious, whereas it=E2=80=99s much pleasanter in org
using org-edit-special, syntax highlighting of src blocks, etc.

The second is that it=E2=80=99s impossible to share without distributing el=
isp
code.  From the twin standpoints of reproducible research and security,
I think org ought to maximize the degree to which export use cases are
sharable without resorting to executing elisp code.  There=E2=80=99s a thre=
shold
beyond which it=E2=80=99s impossible to keep these goals, of course.  But i=
t=E2=80=99s
worth considering how org-latex-classes and friends might adapt to
increase the territory that falls within rather than outside the
Turing-complete boundary.

Just my 2 cents,
