We don't want to attempt to pull stuff out of `/obj/item/attackby`,
because those pieces are part of the related objects' migrations, not
`/obj/item` itself. Attempting to do this causes knockon effects where
things expected to call e.g. `/obj/item/storage/attackby` in the call
chain were not ferried over to the new item interaction code, because
the related objects hadn't actually been migrated over yet.
I've used refactoring /obj/vehicle as the example for migrating
`attackby` methods instead.
