The article cites that it improved some players' scores, and potentially significantly speeded play.
Pros have actually tried this experiment before (it didn't hurt the good putters):
I have been there many times. Clubs broken. No anymore. Golf is very complex movement. But for us recreational golfers from 6 to 24 handicap we need to understand two thing 1. Swing on plane specially on the backswing. Because the most common fault is the too inside backswing. 2, Control the low point of the swing which is 6 inches after the ball.
Please find a pro able to teach you this. Forget about anything else the body is more clever than you think and will adapt to new geometry.
Or at least do this on practice rounds: Put a tee 4 inches after the ball and 2 inches right of the target and try to clip the tee after hitting the ball. If you take the ball and the clip the tee you should hit descent shots. The rest will be clubface control.
But please find a Pro able to you swing on plane and control the low point of the swing.
Imagine a big foot switch under your lead foot. It's old and rusty and needs a lot of pressure to click it on. From the top of your backswing, stomp on that ****er hard as you can.
Don't worry about anything else, literally ignore everything else you need to do, just make your goal getting that nasty, old rusty piece of shit to click on.
