Previously the conversion would fail because struct object is not generally provided for the const version of the type, but because the wrapper would pass down the type unchanged, it would look for exactly that missing template specialization unsuccessfully. This is specifically an issue for std::reference_wrapper because std::cref() returns an std::reference_wrapper<const T>.
