Hi Bastien,

I was thinking that if it were defvard in org.el, say as

(defvar org-export-current-backend nil)

then any code could use (null org-export-current-backend) to test
whether org is currently exporting or not. Otherwise, the code has to be
certain that it has been called during export if it is going to access
the variable.

For example, babel code can get called both during interactive
evaluation with C-c C-c, and also during export. It might be helpful for
that code to be able to inspect the value of org-export-current-backend
to see what the current context is.
