Catcher not returning ball to pitcher

[Dakota]

If this became a common trick to attempt to "draw" a walk, ASA might address it in the rules, but I wouldn't make book on it even then. To me, it is only slightly more "unfair" than the batter doing exactly the same thing to attempt to draw the throw to advance another runner. The rules clearly make this deception legal, requiring the catcher to be aware of the game situation, so why would they make drawing the walk illegal?
