The problem is the crappy math, not the ability heights.
Cap the stats then the cleric and fighter both have max Strength but the cleric has a butt load of spells. 3 spells later and the fighter goes back in the garbage bin. Caps don't fix the problem that no one can even reach the Maximum Dexelterity mod of leather armor without magic. Caps dont fix the fact that there's no way to have decent AC and not take an armor check penalty without magic or rare materials.
Caps don't fix problems when the designers don't pay attention to what they are doing.
