Bollocks. The whole point of supporting non-native image formats is
compatibility with other software. It's a good thing to be able to read
standard compliant images, but it's much more important to be able to
read real life images. We have real life images of both VPC and Hyper-V,
so we need to do our best to support both. Failing that, we need to stay
consistent with older qemu versions.
