Surely you understand all that gobbledygook is to stop any change that someone may be held accountable for.
Have you noticed that the time consuming and therefore expensive Office of Airspace Regulation airspace studies nearly always recommend the status quo.
How would it be possible to do a study on Ballina and not even consider E to 700 agl?
Have you noticed they only employ people in that office who have zero or mis informed knowledge about the North American airspace ? It’s not accident.
