Definitely think we should merge this, looking back it seems the previous change fixed only the actual underlying issue - which was that the functions were incompatible - by adding a wrapper, but the cast itself wasn't removed. Good idea to remove the cast, too, which should reduce the risk that a similar issue gets re-introduced somehow.
