That doesn't really matter.  It's okay if libvirt and QEMU model feature
in a slightly different manner.

For an example, see how kvmclock is changed from a <timer> element to an
option of -cpu.

I think I now agree with the libvirt folks.  The effects of hv_crash are
the same as the effects of <panic>, for example the VM will not anymore
obey the "reboot on BSoD" setting, so it should be added to <panic>.
