I think a dummy may be hard to test and ensure that it works for all possible scenarios. There are also behavioral questions, e.g. what should happen if a user calls Recording::dump on a dummy? 

Throwing an exception creates a burden for users of the API. 

We will need to think some more on how to fix this.
