Yes; that (as I understand it) is why it wasn't an expected use
case for the architecture extensions. The other related thing that
might be surprising for x86-background people is that being
able to present the guest with a virtual CPU that looks like
a pre-virtualization CPU (eg the A9) isn't really an intended
use case either. (The ARM world has much less of the 'everything
must be fully backwards compatible for existing OSes' than x86...)
