Yes, I think it could, albeit calling this a "capability" or "feature"
seems odd (since really the original behavior was bogus/buggy).
But - with sysctl not being a stable interface, is making qemu use
this actually a good idea? I.e. won't we paint ourselves into the
corner of needing to write compatibility wrappers in qemu
whenever XEN_SYSCTL_physinfo (or its libxc wrapper) changes?
