But what is the benefit? We have already documented padding in the
spec, and discussed it so much time... What is the problem with
padding? And why to add 8 bytes for every new feature which needs
only one byte?
Okay, so requiring an 8-

feature to Qcow2 that indicates which allow to use different compression

It is implied that the compression type is set on the image creation and
