There is definitely going to be something done in the aftermath of the Jason Robertson goal when Connor Hellebuyck's mask was knocked off last Friday. Maybe it's as simple as a more aggressive whistle, since GMs recognize goalies need to be protected. In the days since that occurred, there's also been a demand to make sure «mask-off» doesn't get abused or become a strategy. Last season, St. Louis Blues goalie Jordan Binnington received a delay-of-game penalty for removing his mask in a game against the Jets. Another suggestion was making a chin-strap mandatory an attempt that failed in 2014. Goalies refused that as part of the equipment slimdown. «Goalie Gear Nerd» on Twitter made an interesting point, that this wouldn't work anyways because of the way the mask is designed to fall under contact.
