IMHO, all changes to internal interfaces (not only REST APIs, including 
RPC) need a spec, in particular if the payload is changing.
We had the same discussion for the Scheduler API where a new field was 
about to be added to the filter_properties dict. While it's pretty 
trivial, I think we need to go over all that change to see why it's 
needed and if it's backwards compatible.
