There’s a tool that used to be popular in the .NET community called GhostDoc, that did pretty much exactly what you’re describing: rewording the blindingly obvious. I loathed it. But in terms of filling a very specific and all-too-common niche of “My manager’s insisting we do this thing, but has allocated no time to it, and will never spend more than five minutes verifying that it is done” it was excellent. I feel like Google is just creating the next generation of that technology and it will be very effective at solving the same problem.
