Fallback might affect guest or worse whole host performance

Patch deprecates fallback so that we could remove it in future
and ensure that QEMU will provide expected behavior and fail if
it can't use user provided backing file.

Is this deprecation introspectible? Does it need to be?
Do we even need a deprecation period, or can we declare this a bug fix
(it was a bug that we didn't fail outright on an impossible request) and
do it immediately?
If it is not a bug fix, perhaps it could be made introspectible by
having a new boolean parameter to opt in to the failure now, rather than
2 releases from now?
