IMO, at the MLB level most starting pitchers' pace was fine, but some of the relievers were another story...
Many relievers and hitters' quirky OCD adjustments every pitch with multiple granted time outs cause things to drag. The league needed to do something, but I think they will have to adjust the rules. Nobody wants to see a game end with a auto strike or ball.
I'd be in favor of thee strikes (offenses) rule. Each team gets two violations without penalty, but the third time and beyond are called. That puts the onus on the players over the course of the game to maintain the cushion so it doesn't impact the game at a critical moment.
I know all the purist are upset about change, I felt that way initially too - but the game must find a way to be relevant again, and change will be required to get there.
