Hmm, I agree with the 'it's there or not',
Your "add and generate one on '1'" is essentially the mirrored from my
"always generated one if not '0'" (for new or cloned VMs) approach, though.

But, concluding from their docs[1] and Dominiks tests, mine should be the
safer default, it makes sense to have this, it can make cloning safer,
especially for guests running things like a domain controller[0] or databases
- so I'd prefer a default on approach.
