Not really the point. It was developed by Sony and then used later by 3rd party devs. This is the downside of a complicated architecture, devs don't want to get bogged down in tricks. Less dev time means more money.
In the case of MLAA, devs started using the lower IQ FXAA (developed by Nvidia).
I hope FXAA dies with this gen. No matter how much nvidia pushes it, it looks like crap.
