My point is that what is required by an actual real world application is not up to the community. It's up to the universe. For example, if you want to judge the predictions of astronomers about close approaches of asteroids to Earth, the standard is not what the community thinks is ok, but whether their predictions are accurate enough to say for sure whether an asteroid will hit or miss. That standard is imposed by the universe, the laws of physics, and our desire to not get killed by an asteroid impact.
