!! rel-author doesn't mean the same as rev-made eg:

"I have just finished this new  <a rel="author" 
href="http://coolsite.co.uk/">Cool website</a> check it out""

that would mean <http://coolsite.co.uk/> is the author of the referring 
page which is nonsense. rev="author" is clearly better semantics in the 
above case?

And that was the basis of  the whatwg decision to drop rev? (I am not 
criticizing just trying to understand it) surely all it needed was to 
define some rev values (the same as rel) and people will start using rev

There are some cases where that is just not possible.
