A 'deprecation' message implies that the functionality continues to
work, but the user gets a warning that its going away. In this case
the user gets a warning, and the functionality is unusable - qemu-img
just exits immediately. This isn't deprecation in any normal sense,
it is just immediate feature removal with an message telling you it
has already been deleted :-(

Daniel
