No, as explained this point can only be reached if there is some 
creation option for qcow2 images which is not handled by any of the 
branches in this function. Since there is no such thing currently in 
master and there most certainly won't be in 2.2 (thanks to hard freeze), 
it's fine to keep it out of 2.2.
