I wonder why this leading edge design did not trickle down into commercial aircrafts following the IL-62?
I see the advantages of IL-62's wing leading edge protrusions include big savings for cost and maintenance, weight reduction and allowing for bigger wing fuel tanks. Are there disadvantages that prevent that design from being prevalent in commercial aviation?

IL -62's didn't rotate, they levitated off the runway.
