No, but it might eliminate the cheapest certs that people might use. I'd 
like my personal server to have a self-signed cert with it's fingerprint 
handled via DNSSEC, because I don't want to pay a CA.

No, because DNSSEC isn't secured all the way from the DNS server to the 
application, only to the resolver. Both systems have problems, I'd imagine 
the best security is when they work together.
