The issue is heat. Heat, beyond a certain point (which no-one seems to quantify) causes the carbon fibers to oxidize (causing them to weigh less) and lose strength.
So, with CCB rotors, there should be a massive payback for brake-cooling ducts that can keep the rotors "properly" cooled. The problem is that I've not seen what would constitute "properly" ... but it's a given that cooler means longer life, all other things being equal.
