This is your suggested change to the rules? This isn't a case of a crazy coming in on port against a starboard tacker, it is about whether A tacked too close or not. What if this incident had occurred in the middle of the course? If I am leeward boat (on the same tack) and you plan to tack accross my bow, you'd better make sure you can make it without fouling me. If we are both on starboard and you're tacking to port, you gotta stay clear of my path. If we are both on port and you tack to starboard, you gotta give me "room and opportunity." That is all this is about. A had GE pinned on port tack until an opportunity for GE to tack into the clear becomes available.
