Just because you don't use it, doesn't make it useless. Asking why someone would use it is like asking why someone would use the backspace key.
It's an alternative to backtracking through text you would like to remove, while simultaneously allowing you to overwrite it. A time saver to some people that have been using it for years and if they removed it from the standard-101 keyboard, I'd personally be kinda bummed.
