I think of brittleness as a subset of risk. Risk has a very large surface area, and has to be mitigated by a correspondingly large number of techniques. Brittleness seems like a useful subset to address in the context of specific techniques that can avoid it. 'One thing' seems like a useful heuristic in this context.
