I think we are talking about a client or server using setsockopt()
calls. This is not about globally changing TCP engine behavior.

For instance, on a router, I believe that NETCONF, RESTCONF, BGP and LDP could use the same TCP stack, as well as possibly all other TCP-based protocols running on the NE. And if HTTP is included, YANG models have a pretty broad applicability beyond routers. So what makes NETCONF or RESTCONF so special that NETCONF needs its own model?

The models are not NETCONF/RESTCONF specific unless process forces us
to make them NETCONF/RESTCONF specific. What makes NETCONF/RESTCONF
special is that we started this 5 years ago. I do not care at the end
who owns the document as long as process does not bring us more delay.
