We might argue whether bitul chameitz means something other than hefqer.
But even if it does, how can a formula that ends "vehefqer ke'afrah
de'ar'a" not render it *also* hefqer?

I am not sure what kind of qinyan burning would be. (Shinui? but shinui
to something worthless is back to not having anything shaveh perutah to
own.) Taking from hefqer means there is no maqneh, does that mean there
is no qoneh?
