Yes. Unless you want to change the protocol (or the protocols) as
well, which would involve another WG (or even WGs). Perhaps this is
what will happen if we were to start this.

But ideally, we would use a YANG next activity to get the interface
between YANG, the encodings of YANG defined data, and the protocols
better worked out (since we now know that we have several of them to
take care of and we I think we learned where we could have made things
simpler).
