I did ack it, but it's not great that this was just applied and now it's 
being changed. If the submitter doesn't have time to work on it more 
then the maintainers shouldn't really have time to apply it.

'additionalProperties' can't 'see' into the reference. This needs to be 
unevaluatedProperties instead which solves that problem.
