The problem with the rev attribute is that it's difficult for authors to 
understand the concept of a reverse link relationship; and compared with 
rel, it's hardly ever used.

There's only one use of rev that I'm aware of which is listed on 
microformats.org.  It's for vote-links, but I don't think those 
relationships should be used anyway.

I think it should still be present, but it's semantics would need to be 
clarified and explained.  We should probably also identify some real use 
cases where it is actually useful for authors.

Can you more clearly define what you mean by "opaque semantics"?
