YES! Why would that make sense to anyone at Apple. Even if you want to do 4x5 pages (another rant), at least make something bigger than 3x3 folders.
 
iPad Pro having the exact same number of icons per page as iPad Mini looks... odd I have to admit.

I'd expect iOS 10 to revamp the homescreen interface to better fit the Pro's giant screen. Higher density of icons. I also expect it'll trickle down to the Air series too.
 
They should us give the option to choose the amount per page.
We finally got more icons per folder since iOS9 it's a (minor) step.
