Yes that's about it. I disagree about the likelihood that messages or phone calls were exchanged prior to installing TextSecure. And restoring the SMS database after purchasing a new device is not impossible. But I agree that names and addresses wouldn't work, although I didn't suggest so. My point was that it would improve on the status quo, at least for people you care most about (the ones you've talked to, the texts you didn't delete). And once the hashes are hard enough to reverse, you can have a federation of TS servers, because it becomes less risky to share them with an untrusted party. Maybe the improvement would only be marginal after all. Anyway thanks for the discussion.

Looking at the docs and blog posts may give you the impression that certain things are done, when in actuality they're not. For example, the TextSecure-Server does include federation related code, but implementation is definitely not complete yet. It's not clear to me whether or not all design decisions have even been finalized yet. I encourage you to write up your idea more formally and post it on the WhisperSystems mailing list. Just don't wait too long, or Moxie and his gang of contributors will just decide what to do and push working code before you know it!
