Yep. They've been tinkering with the scrum ever since I was a kid, but to me it feels like they result in a collapse, a penalty[0] or one side being totally steamrolled 90% of the time. I wish I had stats at hand to back this up, but I feel like even though they're technically "contested" they're rarely actually contested.

If it's not enjoyable for spectators, doesn't really do much for the game and is dangerous then I can see why it could get phased out in the long run.

[0] = or multiple collapses then a penalty
