your question is a bit too wide, an example case would be helpful. as far as i understand, yes, safety first. however, it should be noted that there're different approaches to achieve different safety level. how "safety" our platform will depend on company's policy. in risk-based approach, there's a certain level where it's unacceptable. if it's unacceptable, you should choose safety. but if it's within acceptable range, there're more to discuss, like the cost, maintainability, etc.

well that's what i understand. anyone?
