Yeah, there's no reason to change it since it's so rare. I can understand the concern about a local guy getting thrown in net against his hometown team, but you just need to run that risk. I get the feeling that the NHL might ultimately consider placing some league hired guy in every town, but eventually shoot it down due to it being a pointless expense.
And as for the goalie coach, I thought about that one, but there's bound to be a few out there who are 50+ years old or who have serious health issues.
