That commit is literally 2 days old. Also this code is executed on all
supported qemus (starting from 1.5.3) so you'd need to be more specific
on the 'quite some time now'.
Additionally this patchset actually stops calling this code path when
blockdev is used so I'm not going to invest into investigating whether
the URI format is really supported on ancient qemus if it's not going to
be used in the future anyways.
