I have a vague recollection that we argued at the time, that if and when the admin twiddles the knob to enable it, then it will be used without any further checking (or emptying) of it at that time, so it is part of the repository state that needs to be correct for the repository (including its knobs) to be considered 'verified good'.  And that still makes sense to me.
