I'll be fine if Stefan and Kevin override me, but yes, I think
consistency is important.  qemu-img has offline functionality equivalent
to block jobs, and it is useful to keep qemu-img subcommands as
consistent as possible between them and with the corresponding HMP
commands.  convert is the equivalent of the online mirroring block job.
