IIHF rules state the play shall be blown dead as soon as an opposing player steps foot in the crease.
I would take it a step further and issue a 2 minute minor for it. We have a two minute minor for shooting the puck over the glass, so why not two minutes for a crease violation.
Your goaltender is arguably the most important player on your team. You generally only have one other one that's not very good, he's on the ice for 60 minutes a game, and usually is one of the highest paid guys on your team.
That's not really the rule - at least, that's not how it's enforced. If an opposing players skates through the crease, it's generally left uncalled. If they stop in the crease, then it's blown dead.
Also, the league tried something similar in the late 90s with the whole "skate in the crease equals no goal" thing, and it was an absolute mess. I have no interest in going back to that, at all.
At most, blow the play dead if there's contact with the goaltender in/near the crease. Anything more than that is overkill.
