Honestly I'm totally fine with this existing as an optional exploiit because it's a thing you can very easily ignore. I like the idea of having things like this in a game particularly because they can give newbies a way to get around challenging encounters and give themselves a leg up. Unlike a lot of the other exploits in the game, this doesn't mess with the D&D rules and its existence doesn't disrupt play unless you want to use it. This is the kind of exploit I consider to be actually a net positive for the game.
