I find it interesting the author didn't mention field hockey. My daughter is a goalkeeper for her youth club. The goalkeepers wear very similar pads, and face shots at similar speeds with the same safety concerns. (I wouldn't want to be hit with a puck or a field hockey ball).
The save percentages are about 70% vs the 90%+ in ice hockey, but the game scores tend to be similar to ice hockey.
If the goalkeeper is getting bigger because of the gear, even adding a few more inches onto the net to maintain the desired scoring percentage makes sense at least at the professional level.
The cage is much larger in field hockey: https://i2.wp.com/hockeyanswered.com/wp-content/uploads/2019...
