There is no global `org-export-format-drawer-function' variable, and
each back-end may provide it. I think the "big four" does it.

Though, it's more a convenience variable provided for compatibility with
legacy exporter. There are other, and more standard, ways to achieve the
same result in the new export engine (filters being one).

Filters are lists of functions, by the way.
