If "a few requests failing isn't a problem" is a reasonable statement in your company then this type of service isn't really aimed at you. The point is to help shake out fault tolerance issues. If you can already tolerate faults there isn't much of an issue.

Well yes, but I would suggest that they are uncommon enough that a few requests failing isn't a problem when those happen.
It's an entirely different story when you are killing processes constantly.

It doesn’t _need_ to be constantly. The important part is that it is done _deliberately_ to understand what happens when failures occur.
