That NNW Greenland coastal crack is quite something! If movement of the 'triangle' is more than a temporary or intermittent thing, this year will be different from at least most years (all? - would have to do research, and not just remember), and yes, 'worst' possibility. The ice there certainly hasn't aged long, compared with most previous years.
There has been many a discussion on the effect a frequently cracking ice pack will have: things like more young ice and more heat loss from the Arctic Ocean, more mobility, higher dispersion (area/extent).
