I would like to avoid a second code path because it comes with a
maintenance cost.

Experience also tells that adding a new way to parse option strings will
come back at us later because it we must always maintain compatibility
with yet another format.

So I would prefer not doing this and just passing command line options
to qemu-tcmu, which can reuse the already existing code paths.
