One of the things that I heard a college coach (former umpire) discuss regarding rules and how to use them to win, was this very situation. He was going through this rule for the catchers and said that the "Batter has the right to the batters box" and that they had to step clear to ensure a good throw. But then he challenged them to think through the fact that slappers more often than not are out of that batters box when throws need to be made to second in the case of the steal. And that when that situation arose their easiest throw for an out, was the back of the slapper and not to second base because in that case the batter did interfere because she has "no right" to be out of the batters box and in the field of play.
That's fine, but if I think the catcher is intentionally playing "dodge softball," we're going to have her ejected for unsportsmanlike conduct. Probably followed by the coach who will more than likely try to "discuss" the point.
