It's logically correct, in that there is no way to pass a non-default location to the target hook, but the location doesn't matter much except for diagnostics options. In due course I'll update the target hook prototype to pass several extra arguments (the main ones being opts and opts_set, but the location and diagnostic kind can be added at the same time as well).
