The problem with advanced modes is that it is easy for a chaos monkey to get into them, and at scale that will happen all the time.

A mitigation for advanced modes is to have a big bright red "get me the hell out of this to a normal state" button. Making it easy for a human to get back to the normal steady-state reduces the risk of an advanced mode and gently encourages exploration and experimentation, if it is always trivial to get back to what you're used to. This means that configuration changes can't ever be fully destructive though, which requires quite a bit of design and engineering.
