Is there a reason we should use RegisterCallback over AddStrongObserver?
It doesn't require creating a separate object to act as an observer. Of course it creates one under the hood for you, so this is mostly a matter of whether calling code ends up simpler or not, not of efficiency.
I have a fresh API where I'm using AddStrongObserver at the moment, but would be happy to switch if that will be cheaper / more future-compatible.
Are you properly handling the fact that AddStrongObserver watches all prefs starting with the prefix you pass it? ;)
