In my day, flying 1st generation heavy jets I always flew VREF + 10kts, easing back to VREF "over the fence". The reason I always gave for this was, it is easier to loose the access speed should the need arise. Try recovering from a sudden 10 knot speed loss when flying VREF.. Also your landing weight maybe higher than you thought. Prevalent during cargo ops..
These days one would probably be reported for an "unstabilized approach" or some other misdemeanor, for the above.
