wrapQtAppsHook out of tree?

Though adding wrapQtAppsHook to nativeBuildInputs should work with stdenv.mkDerivation (see Qt: Do not require mkDerivation by ttuegel · Pull Request #71089 · NixOS/nixpkgs · GitHub).

Maybe it will in the future; but at the moment, wrapQtAppsHook cannot be found in stdenv.mkDerivation.
