The reason you pitch up is to bleed off excess speed during flare.
So how much speed do you actually lose during flare? Is it significant? If you wouldn't flare, what would most likely be the result? A runway overrun?
Maybe next time you land on a long runway, so a few knots more doesn't matter, why not try to land without flaring to see what happens? If flaring is only for speed reduction, it shouldn't matter?
