"...and we actually don't hate the all-clicking trackpad much at all. (If your thumb muscle memory makes you click at the bottom where the button used to be, it works and feels pretty much the same.)"

It /feels/ the same as the old trackpad thus it has tactile feedback. The entire trackpad clicks.
