My main fear with things like this is that using it will get me into a pattern of thinking I'm safe, so that then when I'm doing something on another system that doesn't have this, I'll accidentally make a mistake and won't be able to undo it. This is a fundamental problem with nearly all attempts to make things easier or safer. A lot of what makes things safe or unsafe has to do with our level of attention to what we're doing; conveniences that allow us to reduce our attention can paradoxically make things less safe unless they're baked in at the very lowest level.
