We should update mbox-consumer.yaml and remove this file instead.
There's only a couple of references to it.
We should either just add missing descriptions to mbox-consumer.yaml or
change it to mbox.yaml and add #mbox-cells. The latter would only
provide some completeness as we don't have any constraints
on #mbox-cells (there's a global max of 8 already).
