Questioning the efficacy of rdbd signatures is reasonable but not
at all the same as a claim to not understand 'em.

I agree that the efficacy of these signatures isn't a slam dunk.
The draft says as much. I'd be happy to improve the explanation
in the text wrt that.

But the signatures are optional. So if I'm wrong that they're
useful, then that's ok, you'll be right and they'll not be used.
Equally, if OTOH but unexpectedly, I'm not wrong, then there'll
be a method for signing defined as part of the spec.

What's wrong with that?

Thanks,
S.
