I think I've seen 2 or 3 actual hip drops in my 40 years of watching RL. The modern day proliferation of this kind of tackle has been created by the single minded battle between attackers prioritising finding their front and defenders prioritising putting the ball runner on their back.
The priority should be metres for both parties. If the time of a PTB was standardised a lot of the BS in the ruck would go away. The constant battle to control the ruck is the biggest blight on RL. I'd love to see a game where every PTB was equal. It would prioritise attack and incentivise low tackles.
The speed of the ruck shouldn't be the be all and end all.
