This was actually what I was worried about with this flag rule. The original intention was to allow for players with a putt on the front of the green the ability to putt to a back pin without fear of getting a 2 stroke penalty if they happen to hit the pin.
With the discussion changing to how the rule can give a competitive advantage, especially on tour I was worried it would slow down play. In a recent article, I wrote about a scenario where Bryson and Justin Thomas are paired together. One wants to leave it in, and one has been quoted saying he can't take himself seriously if he did. I'm sure this will play out on tour more than once.
All this considered, I still think we can agree that the need for juggling the flagstick still seems a little odd.
