Your statement in response here, where you say that if you use this omission means non-inclusion, seems to contradict this statement in the comments:
> The whitelists and blacklists still work and are still applied.

And as to this statement:
> And there is no wildcard to allow all fields in a particular model.
Is that something that was intentionally removed?
