For reference, here are the relevant threads on libvir-list:

v1:
https://www.redhat.com/archives/libvir-list/2021-January/msg00601.html
v2:
https://www.redhat.com/archives/libvir-list/2021-January/msg00684.html

And my objection to use 'x-' prefixed features without being guaranteed
that it's considered stable (note that the premise is that it's supposed
to fix already-released qemu versions thus not completely refusing using
the existing naming)
