Well, you can implement such checks within the same function :)

We would need to rename `org-export-format-drawer-function' to 
suggest it can be a list of functions -- I don't want to go into
this direction right now, I need to double-check what the new
exporter (contrib/lisp/org-export.el) does wrt this.

Nicolas, how the new exporter handle this?

Yes, `org-export-format-drawer-function' supports only one function.
