We wish to make management hypercalls as the root user in userspace

having /proc/xen/privcmd accept an ioctl() that takes a structure

describe the register arguments. The kernel interface allows us to
control who in userspace can execute hypercalls.
ioctls on proc is evil though (so is ioctl-on-sysfs). It's a device not
a proc file!
I full heartedly agree with you :-)
