You may not trust it but you haven't I believe looked into this case. In which case your judgement is premature.
I won't argue against your intuition or gut feel for this, which I accept as understandable. Nor that I know that you are wrong.
Having understood the arguments for this, I believe it needs testing because it is a thing worth having.
