No longer portable, and given the current state of implementation, no
longer bootable, since we don't support persistent storage yet;
certainly not on OpenStack? Or do we have that now?

Are we really pushing ahead with a specification that nobody can
implement today? How far away are we from a fully compliant

The spec says SHOULD, so I think it's fine. While support for persistent variables in the KVM stack is in the early stages, there is request and it is not ARM-specific. It will be implemented sooner rather than later at least at the libvirt level, and I suppose qemu-arm, xl, OpenStack/, Virt, XenServer and everything else will follow soon.
