I think the primary lesson team have to take from the Tigers is that if the back of the rotation is weak, and you can match an opposite hand reliever with one of your weak starters, the you clearly get an advantage in platoon splits. All you need to exploit the strategy is a deep bullpen, since you are burning one extra pitcher at the start of the game, but deep bullpens are pretty much a standard requirement today anyway.
If the league doesn't step in to stop the practice, I can't see why other teams won't follow. Then eventually teams will respond on the other side of the ball by increasing their valuation of switch hitters and/or hitters with lower platoon splits,
