Using Atom elements in RSS feeds

I'm curious -- what are RSS1 people's reactions to using Atom  
elements in RSS feeds?

I ask because I'm designing an extension that can be used (currently)  
in both Atom and RSS feeds -- Feed History <http://www.ietf.org/ 
internet-drafts/draft-nottingham-atompub-feed-history-04.txt>. It  
defines three elements, one of which is in the form:
   <fh:prev>http://www.example.com/foo/1</fh:prev>

Some Atom WG members argue that this should be:
   <atom:link rel="prev" href="http://www.example.com/foo/1</fh:prev>
and point out that other specs already use Atom elements in RSS feeds.

It's obviously not ideal (you'd need to declare two namespaces to use  
the extension in RSS -- one for atom, one for the other elements),  
but I'd prefer, if at all possible, to avoid having one element for  
RSS feeds and a different one for Atom feeds.

What are people's reactions to this? What's the lesser of two evils  
-- using Atom elements in RSS, or having separate elements for  
different formats?

Cheers,
