Do you have anything more solid?

I read something from BMW about specific cleaning processes for CCB and not allowing, as an example, road salt to remain on the rotors. That sort of stuff reminds me of the work needed to maintain matte paint. This is one of the reasons (excluding cost) why I personally chose to not go CCB... I wouldn't want to drive the car all winter and expose it to the salt, sand, etc of a typical Canadian winter. It may have been fine but reading this concerned me. If it was a summer only car, then it's a different story.
The maintenance items like these and the concern over the rotors being more fragile worried me personally. It would be good to confirm whether these concerns are truly meaningful, however, or if it is not a real issue. I am almost certain I read the salt/cleaning/maintenance piece directly from BMW when I was scoping out my M4 build but I can't put my fingers on it now.
