I think you are right, however its that same lack of enthusiasm that
would hamper a DPDK 1.0 specification. Similarly I can see a DPDK 1.0
specification effort becoming an endless process, as it would always be
low on DPDK contributors priority list.

Instead I recommend we set an API freeze date to focus peoples minds,
advertise what it means and contributors will respond and look after the
areas they care/are responsible for.
