Again, both of these apply to when Android and the original ROM are still installed. So, if your phone gets stolen by someone who knows how to root a phone and use the recovery, he could backup all of your data, flash a new ROM through recovery and now he has a new phone with no apps, lockscreen, or Superuser app to deny permissions to root. With the backed-up data, he could sift through that and possibly find personal data.
However, the lockscreen will be successful against entry if the person doesn't know how to use the recovery. Superuser rights can't be granted if it can't pass the lockscreen. And right now, I have no permissions granted to ADB shell or Terminal Emulator.
I know some people may think, "what is this guy thinking, he's an idiot, etc..." but I am thinking of worst case scenarios in a security perspective in regard to data protection.
