So next year we get 3v3 OT, coaches challenges (Haven't heard how many yet) for GI and Offsides goals. GI is interesting because that's a judgement call, afaik that makes them the first sport to allow review and overturn of judgment calls. If you're going to review that why not review a hook on a breakaway that could have been a penalty shot, or a DOG that led to a 5 on 3 for 1:30; both also judgement calls that can be just as important in leading to goals as GI.
