The intent of XEP-33 was to mirror the multi-address approach of  
SMTP.  I actually took the original field names directly from RFC  
2822, IIRC.  Repeaters are more like a mailing list, if there was a  
standardized protocol for lists to be created on the fly.  Seeing as  
how the intent was so different, it made sense to start from scratch.

Putting my implementor hat on, I really dislike it when specs have  
drastic changes that could have been put in a separate XEP (I'm  
looking at you, XEP-60), since it makes managing compatibility for  
shipping code quite difficult.  Some guidelines I strive for in  
protocol design: Proper layers.  Extend by extension.  Break  
compatibility explicitly, never implicitly.  Be willing to admit when  
something new is needed.
