Waze definitely does this[1]. As a map editor, I can mark a road segment as closed and it will stay closed for as long as I say, unless reverted by another editor or traffic is observed moving through that closed segment (based on parameters that they set).
This kind of cheating usually works extremely well, from my observation.
Anyhow, Google owns Waze and data goes back and forth between there and Google Maps. They're like two heads of the same snake, so it's implicit that the same thing also works on Google Maps.
