I am using org-babel (+ perl) to gather a page containing the content of
the most recent posts. I also export this page to rss via ox-rss.el. I
could simply use a perl script to generate the file during the export
process, but a babel source block makes it convenient to modify the text
before and after the dynamic content and to test modifications to the
code.

To generate dynamic content for just one page, babel works fine.
However, if I wanted to update every page with such content, it would
make *much* more sense (as you suggest) to create an exporter.

That sounds interesting. I look forward to hearing more!

Thanks for the clarification!
