How was it more useful? Take note of the blank space around the clock and other icons.The status bar isn't something that is pushing things down significantly though and its previous symmetrical layout means it's actually more useful and predicable in its operation than in notch form.
As opposed to that wasted space, I now have a camera and sensors. The only issue with the current status area on the X, is that apple made it taller (for no obvious reason) for their suggested safe area.
