Well, as I have just again experienced, PA is pretty much the only good way for a Str fighter to vary his fighting style. In other words, a Str fighter without PA will just keep rolling and doing pretty much always the same damage no matter if he catches his opponent with their pants down or not. The extra-high BAB of a Fighter class does nothing for you either.
So in other words, PA is very important for the game, and banning it would make combat very boring for Str fighters. So it needs to stay in effect. However, making it an open Maneuver instead of a feat would of course be possible, thereby also making the Special Attack feats more easily accessible.
