Interesting video on LPVO. Kyle Defoor calls them "the way of the dinosaur" at about 14:02. He also calls the reluctance to change similar to guys reluctance to change from Iron Sights to Red dots back in the 90s and early 2000s.
Video is worth a watch. I have been going back and forth between what I want of my carbine personally and thought a discussion could be insightful and fun.
