Review comment:
I'm not backtracking what I said earlier. It's fine to defined an API, but
the API needs to be well-thought, which doesn't seem to be the case here.
That's why I said we can forgo the API. If we think an API is the way to go,
then let's define the API better and parent class shouldn't define what
validation a subclass might do. Personally, I don't feel the API is
sufficiently sound, but feel free to get 2nd opinion though.
