One doesn't want to be eking out more and more flare, nose getting way high, with stall horn blaring (in a certified aircraft), more likely to get drifted by crosswinds -- especially if one has already straightened out, as one might not know whether it will be 1 or 4 more seconds before for the plane runs out of lift and drops the last couple inches to the ground. Going for the absolute minimum speed leaves the plane susceptible to every little bit of turbulence or gust. Fun to do in very calm or zero turbulence conditions, but not for everyday.
Sorry pchapman but airspeed = lift: too high an airspeed assists any gust and will not prevent it albeit the controls are very marginally more effective.. At some point you must land; the aeroplane need not be kicked straight early. a little late will do no harm to a safe landing. Once in contact with the runway then the aircraft is most vulnerable to gusts if the speed is too fast. You need to be as heavy as possible on touchdown and this will be at the lowest speed and with the most effective braking. Landing too early, too fast and the aircraft is light and the application of brakes will be unpredictable and may be asymmetrical in effect should the weight from the wheels not be equal.
