Great to see this. Seems I can bury my ad-hoc script soon. :-)

About the qcow2 tests there is one thing to note: These test cases use
hard coded offsets which were calculated for 4k clusters. For 64k
clusters (which the default now) I'm almost sure they don't test the
critical points any more. So we'll need to change offsets dynamically
depending on the cluster size of the qcow2 image.
