Yeah - shifts in the NHL used to last for several minutes at a time back before the ‘80’s. Back before the ‘70’s, you had to serve your full 2 minutes for penalties, regardless of whether the other team scored on the PP.
The NBA didn’t used to have a shot clock. You couldn’t play zone defense (note: I’m not sure if you can now, because I don’t follow the NBA whatsoever)
MLB didn’t have a DH, and pitchers pitched complete games, every 4 days. Hitters didn’t wear helmets.
Times change. I think this rule is dumb and unnecessary, but we’ll all move on after some pointless bellyaching.
