It's as meaningful as entity(e) in:

 entity(e)
 agent(e)

and :

wasGeneratedBy([], e)
entity(e)

(Oh, you know the entity was created! Can we have non-created entities?)


But I agree, we could put in a little disclaimer in those cases where
it looks like you can optionalize yourself out of not actually having
much of an assertion record anymore.
