I guess they wasted all that money & time to have the cantilevered wing since it has no effect. As a matter of fact, the stall speed does increase significantly and the approach speed does increase 50 -75 knots even if the leading edge slats (flaps) and trailing edge flaps can be deployed, which is why, in such a configuration, the barrier is erected on board the carrier to assist in bringing the Crusader to a halt besides the normal arresting gear (which, if set for that speed of the F-8, would pull the hook out of the plane) as was done on the Coral Sea in '73 with Mark Weatherup at the controls (I was flying Whales during that time. Whale = EKA-3B.
