I think i can speak for almost all of the hockey world when I say no one likes the NHL's Commissioner Gary Bettman. However, despite how much he's disliked, we can all agree that Bettman does a fair job trying to improve players safety.
With all the recent injuries players have been suffering due to getting hit in the face by sticks and such, the NHL is looking at a rule to help make things safer for the players. This comes from 32 Thoughts podcast host Jeff Marek who was recently quoted as saying:
It will be interesting to see, yes we want all players to be safe as possible but if a full face shield rule comes into the League this would be the end of fighting in the NHL, and I don't think many fans are players would like that.
