Yes, but there are some compensating pluses: You can get a meaningful improvement to your security by good choice of registrar (and registry if you have flexibility in your choice of name). Other weak registries and registrars don't reduce your DNSSEC security, whereas PKIX is only as secure as the weakest CA. DNSSEC has tricky timing requirements for key rollovers. This makes it hard to steal a domain without causing validation failures. An attacker can use a compromise of your DNS infrastructure to get a certificate from a conventional CA, just as much as they could compromise DNSSEC-based service authentication.
