It is perfectly possible to engineer for faster cycles without losing control over what your code can and can not do. It is harder, for sure. But I do not think

It is perfectly possible to engineer for faster cycles without losing control over what your code can and can not do. It is harder, for sure. But I do not think it is a matter of this absolutely not working, that's black-and-white and it never is black and white, it is always some shade of gray. For instance: validating a configuration before loading it is fairly standard practice, as are smoke tests and gradual roll-outs. Configuration fuck-ups are fairly common so you engineer with that in mind.
