even if arakune does avoid a yukikaze, you have to remember you're totally invulnerable until the end and arakune is losing curse meter the entire time. i think it's somewhat useful. yukikaze is also active on frame 1 so it can catch things that things like 623D and 623C would miss (since they recover in time to block). granted taht still doesn't make yukikaze very good, but it has its uses.
Against Litchi, if she sets up 13 orphans when you're knocked down, you can neutral tech, yukikaze to get out of the mixup (though you probably won't hit litchi at all). Similarily, if carl does the same thing with gear super, you can do this too. In both of these situations, a normal dragon punch might hit the opponent, but you will get hit the the opponent's super afterwards.
also, iirc unlimited hakumen's yukikaze comes out even if he doesn't counter anything but becomes blockable. i would imagine the same being for unlimited jin's yukikaze.
