There are numerous issues. A puck isn't a sphere like a soccer ball, meaning you need to know the puck's relative position to the goal line in 3 dimensions to determine if the puck completely crossed a line.
A puck takes a lot more abuse than a soccer ball.
100 mph slap shots into plexiglass, crossbar, posts
sharp blades stepping on it
rubber needs to be frozen or it bounces.
Electronics don't typically survive well in these conditions.
These should be workable solutions, but until someone invests some money into developing a system designed that can meet the requirements of hockey, it appears that it will be a pipe dream.
A camera based system is not really tenable in hockey. With bodies and equipment everywhere, most of the time a puck is not visible to the cameras. It might have helped on Bennett's non-goal though as there were clear line of sights in that particular instance.
