Yeah, not sure that's a real thing anymore. It's either a foul or not a foul. I know what you're talking about but that is not the criteria on determining the foul. Players will still screen the ball and see it out or see it back to the keeper but they're also savvy enough to do so without creating contact with the opponent trying to get the ball. More often than not you see the opponent run the defender over. Now, you will see a player play a touch around a defender and the defender step in on a poor challenge and the attacker will run into the defender. This is a simple foul. If the ref deems it was intentional and prevented a promising attack, then the defender can be shown a yellow. In any case, this is always a direct free kick and if the foul occurred in the box, it's a PK. The only instances you will see an indirect free kick in the box for the attacking team are the situations mentioned previously.
