This is now implemented in a new library in contrib, ox-extras.  This is
intended as a semi-official, semi-curated repository for helpful pieces of
org export hooks and customizations.  Differently than worg, the aim is to
make it easy for users to load the snippets through the ox-extras-activate
function.  Even so, I hope this will be an “executable wiki” where anyone
(who has commit access to the org repo) is free to contribute new hook
functions and improve existing ones.

In the present case, if you execute

(ox-extras-activate '(latex-header-blocks))

you will be able to use blocks of the following form:

#+header: :header yes
#+begin_latex
  \foo{}
  \bar{}
#+end_latex

These will be transformed so that the begin/end wrapper is removed and
each line is prepended with #+latex_header: on export.  They can be
edited as latex code with the usual org-edit-special function (C-c ').

The #+header: :header yes line is a bit confusing.  The first #+header:
is part of org syntax that allows us to tag blocks (and other elements)
with plists.  The :header yes in the plist indicates that this block
should be treated as a latex_header, and not a normal type of latex
block.

Thanks,
