But at least you have the option to switch away from the corrupt
registry operator. An expensive option, since it would involve changing
your domain names, but an option you don't have with x509 (well, you can
switch, but that doesn't protect you, which was the point). Far from
perfect, but for that specific problem much better than the current x509
model.
