agreed.

PKIX, per se, does not have the trust problems that seem to motivate
CT; the Web PKI does. That PKI has always had a serious problem because
any TA can issue a cert for any Subject, irrespective of the Subject name.
because DNSSEC intrinsically incorporate the equivalent of PKIX Name
Constraints, it does not suffer from that specific problem. That's not to
say that mis-issuance is not possible in DNSSEC, but rather that its
effects are more limited.

maybe.

I'll defer to DNS experts on that.
