Perhaps I don't quite understand your question but in my opinion the working characteristics/traits of a well bred rottweiler are
THERE regardless of whether someone's interest is in conformation or whatever venue they chose to work their dog. I don't think that a rottweiler could be a rottweiler in the truest definition of the breed unless it was a working dog.
I think it primarily goes back to what the owner or breeders interest is in the venues they pursue with their dogs.
My primary interest is conformation however my dogs do also work.....its just not something that we pursue formally because its not something that interests me. Will my dogs herd my cattle for me....yup, will a couple of them pull a cart with split firewood on it...yup, can they track a coyote that killed a couple of chickens and hold it at bay until I get there...yup, will a couple of them pull a sleigh in the wintertime with square hay bales on it....yup; does it interest me in pursuing formal carting/tracking or herding tests.....not especially.
I don't think you can own a rottweiler without also having a working dog. Three of my girls are so high drive that I'm sure they would drive me insane if they weren't doing something.
I think the working drives are already in a well bred rottweiler regardless of the venue that the owner chooses to participate in.
