The converter or better 'fixer' actually doesn't need to be able to
interpret the old string, just accept a new. IOW it's more of a
documentation problem, because qemu-img can already do that since it's
able to write invalid JSON without interpreting it:
[...]
I forgot to add that such strings would be user-originated in the first
place. The qemu-generated one are (presumably) correct JSON.
