Now that I think about it more, it's even worse than that. A bogus non-DNSSEC resolution and a forged cert, both of which are real-life attacks that have actually happened, and you're done for. Compromising an IP isn't really necessary if you're going to hang on to a bad one forever, but it's a nice add-on. It removes the need to take out the DNS provider, but we can clearly see that that is possible.
Keeping the balance between security and convenience is difficult on the best of days. Today is not one of them. :/
It's part of what I would use them for. A big, splashy attack distracts a bunch of people while you MITM something important with a forged cert? Great way to steal a bunch of credentials with something that leaves relatively few traces while the security people are distracted.
