I also view it as a perk to being a quick team. If you've left all the officials behind, and still produce flat passes, then it's a perk to be allowed them.
I get frustrated when tries like that get struck off, for slightly forward passes, despite the fact that it gives no advantage to the attacking team. I get it when the forward pass allows a player to have run beyond, or level to the defensive line, and thus can make a break, but no one was going to stop bassett whether the pass was flat a foot back, or a foot forawrds.
I'm not saying we should let obvious forwards passes go, but if none of the officials picked up on it or were suspicious enough to check, I don't want the TMO interfering.
