Not really, but

  (if (boundp 'org-export-current-backend) org-export-current-backend nil)

->

  (org-bound-and-true-p org-export-current-backend)

It should also be documented. In particular, outside any export process,
you need to use ((nil) ...) or (t ...).

Of course. I'm just pointing out that /if/ its only use is for :file
directive, it might be better to include it there.
