I doubt anybody uses this, and it does expose addresses that should be randomized, so let's just remove the code. It's old and traditional, and it used to be cute, but we should have removed this long ago. If it turns out anybody notices and this breaks something, we'll have to revert this, and maybe we'll end up using other approaches instead (using %pK or similar). But removing unnecessary code is always the preferred option.
