I agree with Eric on the above. And a similar thing is true
of the DS record for DNSSEC. And there's no evidence I've
seen that either is remotely practical for the vast majority
of 2LDs. (A few exceptional TLDs aside.) That's really a
pity, and I'd love to see things improve but that's where we
seem to be and have been for years.

Cheers,
S.
