I don't believe that is necessary. A small amount of water left in the bottom of a water line can freeze and not harm anything.
I certainly agree. the question is how do you know that there is no low spot, nook or cranny that water adhering to the tubing sides won't flow back to. I don't care if every drop is out of my water tank since that can easily expand upwards instead of breaking. but as old whats his name said, "do you feel lucky"? I'll spend the $6 and feel safer myself.
