Exactly so. Even if you decide to wait for your browser vendor to remove a notary from their trusted list before you stop trusting it, you'll find this happening enormously more often than browser vendors are removing CAs. You cannot remove a CA without breaking all of the sites that use that CA, while you can remove a notary without breaking anything.

Good security practices are fine (and should be absolutely requisite for CAs), but do nothing to address the real problem with CAs, which is anchored trust. I hope that all of the browsers move to implement Convergence.
