What? There definitely are cases where you don't need to know that to the T. Just think of the - quite frequently happening - need to promote a standby to run tests or reporting queries that can't be run on a standby. Sure, you shouldn't use it if you expect a very specific set of the data being there, but that's not always necessary. And that's why it should never, ever be the default.
