Igore- 

These are building blocks and you cannot conclude on a full solution by
cherry picking part of the overall solution. In another draft that we
discussed via the email
draft-ali-ccamp-rc-objective-function-metric-bound, we talk about client
requesting metric bound (e.g., latency bound). So yes, connection
requirements are driven by the clients.
