Thanks for taking a read!

And even more thanks for reading it twice! It is short,
luckily:-)

Great that you think it's uncrazy.

Yep. Actually in exchanges with John Levine on the dbound
list, (he was v. reasonably questioning the value of these
new signatures), I myself only copped on that this could
be of some use where the primary has DNSSEC but where the
secondary doesn't, which is maybe interesting.

Those mails are here [1] if someone's interested.

Yep. After both domains have DNSSEC, then this could all be
simpler. Before they do, there may be value in the sigs though
see John's simplification suggestion at [1].

Cheers,
S.
