My impression is that this is more about publishing tree head hashes as a way of promising that you have nothing up your sleeve. You can't remove something after someone has depended on that value being there without someone noticing. The certificate transparency comparison is helpful. If it's append only, you should be able to find the old head in the log. Not sure if that is what it's going for though. I'm still a bit confused by this myself.
