The information which BB is concerned does not seem useful enough to justify its existence in most other place (which may be related to qemu printing the -drive parameter in question anyway, and for blockdev-add the attribution is naturally unambiguous). Furthermore, as of a future patch, bdrv_get_device_name(bs) will always return the empty string before bdrv_open_inherit() returns.
Therefore, just dropping that information seems to be the best course of action.
