Safety is not so much the issue. A few knots above Vapp has a huge effect on flare characteristics of this aircraft ánd on top of that provides you with margin to avoid planting it in when the wind drops out on you in the flare like it always does in for example AMS runway 06. Ground speed mini has long gone to bed at that stage.

Simply put it is far far far more forgiving with a ‘couple of knots’ extra.
Sure you can fly at VLS, but you give away a lot of handling margin for what, 60 meters less landing distance?
