That doesn't strike me as a problem.  There could still be a pointer to a client-managed progress state along with the internal state, just need to copy data into the former before invoking v1 callback.

Overall, a more convenient callback just doesn't seem to me like a good enough reason for breaking any compatibility.  On the other hand, repology.org shows only a single `libflashrom` package.
