This RFC is lgtm.

I wonder how it corresponds with capability negotiations. If we
have capability negotiations, we don't need iproto_error_stack
*and* iproto_error messages in the protocol, we can negotiate with
the client whether or not it's ready to receive
iproto_error_stack.

However, I think capability negotiation in client-server protocol
is an overkill. Gradually phasing out old client support is a cleaner
strategy. And simply preserving backward compatibility, which is
already possible with extra fields ignored by old clients, is even better.
