There are also two new error codes - 'no-route' and 'no-consumers', 
which need to be used in place of more generic errors in 0-8.

I like that idea.

We'd need to do a careful comparison of the *text* of the spec. Things 
like new methods and fields are easy to spot and easy to implement (at 
least as stubs), but subtle changes/clarifications to the semantics are 
much harder to identify.
