Perhaps you are willing to entirely ignore the intent of
what I'm saying and only try score pointless points? It
does seem like that from this side TBH, but nonetheless...

I always said "with integrity." Such integrity can be
built up over years if there is no key rotation. Or it can
be provided via DNSSEC independent of RBDB key rotations,
which has more or less the same effect. That is all very
straightforward. And I believe you do already understand
that, so I remain utterly perplexed as to how you could
possibly remain confused.

At this point, it might be a stylish possibility for you
to say "yeah, I was just testing the limits of your own
understanding of your proposed scheme";-)

Cheers,
