When did this whole lying down with your foot in the dead ball area, or in touch, become fashionable?
I'm sure law changes did not result in it being the norm, well at least I hope so. I really think the laws need to be changed so that it is no longer allowed. It takes away a great aspect of the game as a spectator where you used to wait in anticipation to see if the ball would stop just inside the dead ball line or whether it'd roll dead. Now some player just spoils all the fun and lies with his foot over the line and grabs the ball which is still over a metre in field!
The only time the ball should be allowed to be fielded in field and then taken out is if you take the player is in the air.

If you're referring to du Preez winning a line out, you evidently don't know too much about the modern rules...
