It's the natural thing for services to be brittle. We're all human after all: a mistake in recruitment, hiring, training, scoping, managing, documenting, or etc. can cause an engineer to make the mistakes needed to make a brittle service you might rely on and that's something I think we can all agree is something you just need to accept as "going to happen."
In that case it's worth dealing with it as it is not how it should be.
