This is one point I agree completely with.

There's no reason to couple the decision to "move something to an
external file" with making changes to the Qemu external interfaces.

We should be able to gradually move things to be "data" without breaking
the expectations of libvirt at the same time. We must be able to make a
gradual design change, where we first move data to an external file
without making that change visible to the outside, then slowly try to
make it part of the user-visible configuration (that means making
externally visible interface changes, something that has to be made much
more carefully than just moving "internal data" around). Anthony seems
to be simply rejecting the possibility of doing this gradual change[1].
