I doubt that this (or anything similar) introduced will even be set to
on by default. It has the potential of breaking stuff that would work
otherwise (thats why the default boot is with the safest configuration
possible).

I was planning to implementing it by probing the image before actually
booting it.
This process is completely offline and doesn't require interaction with
the guest. The guest isn't even running at that point.
