This is a valid explanation, however then you have still included the
time or the attributes, and not covering Tim's question.

However, I don't see any reason why we need to spend effort making
wasGeneratedBy(e) 'forbidden' - it could still be used with a note if
someone wants to give metadata about the generation (say why the
activity and time could not be recorded!)
