Did you read the RFC? I mean what the RFCs say it means:

The RFC first defines the contemporary view, then they recommend  
formally affirming it.

I know what they mean: they refer to what I get when I follow that  
link.  They have a concrete realization, not just an abstract  
idealization.  It avoids all sorts of nasty epistemic hairballs;  
plus, in case of doubt I can just follow the darn link and get *some*  

Is it a huge deal?  Maybe not, but its a great convenience.
