After taking on IRC, I understood the point.

I indeed will send another patch after this one that will
only cleanup qcow2 amend/create options and then patch that
adds luks amend to qcow2, thus 3 patches in total, this one,
the patch that cleans the create/amend separation and then
patch that adds luks amend to qcow2.
