Just to be clear upfront so that you don't waste your time: A new native
image format is not going to be merged. You would have to prove that
your format is capable of replacing qcow2 with all its features, that
it's better in some respect and that qcow2 cannot be extended to provide
the same. Other proposals, including FVD, have failed to provide that
and I'd consider it unlikely to happen this time. (QED fell short of it
and was merged anyway for political reasons; it's clear today that this
was a mistake.)
