That's true. I did it while implementing a webservice that could also
return html in some cases, not a proper web site.

Still, I don't see how this is more flexible. Your "...more
processing..." block could be inside the 'render_html' function
anyway.
Moreover, the whole if..elif thing is kind of rigid. There are cases
where more than one of the ?_requested() functions would return true.
For instance, a browser's typical Accept header allows html, xhtml,
plain text, xml or anything else, but with different priorities. With
your approach, you would end up returning the first (and not
necessarily the best) condition met.
