You almost sound like Dan refused to consider anything but parsing help
output, like it were Dan's fault that QEMU still doesn't provide a
usable interface for querying its capabilities, and like the way to get
it was to put more pressure on Dan.

That would be unfair.  Dan posted patches to fix this problem properly,
which puts the ball squarely in our court.  Could we please refrain from
gratuitously fscking up libvirt just a bit longer, until we finish
improving and merging Dan's patches?
