My understanding is that Winer's main interest has always been outliners, and RSS etc. were just fortunate side excursions, so I find it about as boggling as the phenomenon that people with hammers are likely to be pushing Open Nail Markup Languages.
But semantics… RSS is flat and items are usually ordered by pubdate. OPML is better suited for relatively static collections of things organised in a tree. Using OPML to store blogrolls makes sense (but is not the only viable option of course).
